: Who the hell's dumb enough to fly up a blind canyon below the rim? One day in 2002 two owners flew their "forked-tailed doctor killers" up a blind canyon in southern California: http://www.ntsb.gov/ntsb/GenPDF.asp?...02FA211&rpt=fa On June 30, 2002, about 1059 Pacific daylight time, a Beech V-35A, N156U, collided with mountainous terrain while maneuvering in a canyon near Ojai, California. The pilot/owner was operating the airplane under the provisions of 14 CFR Part 91. The commercial pilot, one pilot rated passenger, and another passenger sustained fatal injuries; the airplane was destroyed. The personal cross-country flight departed Van Nuys (VNY), California, about 1030, en route to Oceano (L52), California. Visual meteorological conditions prevailed, and no flight plan had been filed. The primary wreckage was at 34 degrees 33.503 minutes north latitude and 119 degrees 28.139 minutes west longitude. A witness reported that the pilot was one of a group that routinely gathered on weekends for local flights. They all met at Van Nuys about 0930 for a preflight briefing. The accident pilot was to be the lead, and he obtained a weather brief. He then briefed the group on weather, communications, route, altitudes, alternates, and safety issues. The flight consisted of a group of eight airplanes. The airplanes departed as three groups in formation. Two groups consisted of three airplanes, and a third group consisted of just two airplanes. The group formed up at 4,500 feet. The witness reported that after flying around the area for about 25 minutes, the lead instructed everyone to separate and follow in trail. The lead and the number two airplane stayed in formation with the second airplane on the right wing. The rest of the airplanes followed in loose trail as the leader maneuvered in a serpentine manner. The flight was now over the Ojai area and proceeded on a northerly heading. Members of the group reported that they had flown in this area before. Witnesses reported that the first two airplanes separated from the rest of the group. They descended into a canyon to an estimated 500 to 1,000 feet above ground level (agl). The other airplanes followed about 500 feet behind the airplane that they were following. The number three pilot estimated that he was about 200 feet above the leader's altitude and number two was between them. Number three was flying at 120 knots and heard "90." He noticed that number two was getting closer to the leader, and he was closing on number two. As the airplanes proceeded toward the end of the canyon, number three noticed that the terrain was rising, and the canyon was getting narrow. Due to his concern about terrain clearance, he decided to exit the formation. He asked the leader if he was going to make it, but he had his microphone keyed and did not hear a response. Other pilots heard someone say, "I don't think so." A few seconds later, number three initiated a hard pull up to the left and began to climb. He completed about 15 degrees of turn and saw the lead airplane collide with trees and terrain at his 2-o'clock position. The number two airplane was a little to the right of the lead when it also collided with the terrain. The lead airplane caught fire and then the second airplane caught fire. The second airplane was N576Q, a Beech S35; see NTSB accident report LAX02FA212. Number three estimated that the ridgeline elevation was 6,000 feet, and he cleared the ridgeline by 50 feet. He noted an outside air temperature of 87 degrees Fahrenheit. He immediately notified authorities in Santa Barbara, California, and entered an orbit at 8,000 feet. Within 7 to 8 minutes a helicopter arrived and dropped water on the fire. About 20 minutes later several aircraft arrived on scene and number 3 departed the area. While I wouldn't characterize him as dumb, there's the tragic tale of stunt pilot Frank Tallman: Frank Tallman, (EAA 75) returning from a flight to northern California scouting movie locations, was killed when his Piper Aztec hit near the top of the Santa Ana Mountains east of El Toro Marine air base, southeast of Los Angeles. Died April 16, 1978 Frank Gifford Tallman III The coroner's report said that he died of a heart attack in flight. 04/15/78 TRABUCO CANYON,CA N5641Y PIPER PA-23 FATAL (1) 33 40N 117 28W UNKNOWN AZTEC N5641Y WHITE W/YELLOW TRIM N-Number: 5641Y Aircraft Make: Piper Aircraft Model: PA-23-250 Serial Number: 27-2755 Year Manufactured: 1965 Aircraft Type: Land Engine Make: Lycoming Engine Model: TI0-540 SER Horsepower: 310 Airworthiness Class: Standard Seats: 6 Type of Ownership: Corporation Owner Name: Sale Reported Street: 11962 S Prairie Ave City: Hawthorne, CA 90250 FAA Region: Western-Pacific Country: US Last Activity Date: 16-Aug-1980 Frank Tallman succumbed as chronicled in NTSB report LAX78FA043. Below are some newspaper articles which appeared subsequent to Mr. Tallman's death: Tallman had over 21,000 flying hours by the time of his death. HE HAD PILOTED MORE THAN 500 DIFFERENT KINDS OF POWERED, FIXED-WING, AIRCRAFT, HELICOPTERS, GLIDERS, AND BALLOONS. "He had just refueled in Santa Monica, there are no,indications of any pre-impact mechanical malfunctions, he had had plenty of sleep, he was not taking any medicine, and the autopsy and toxicological tests all came up negative." Tallman had departed San Francisco earlier in the day, flown to the Salinas VOR south of the Bay Area and then followed the coast to Santa Monica, flying most of the time at less than 1,000 feet. A flight between Santa Monica and Phoenix: Tallman dropped off his sole passenger at Santa Monica and departed for the Phoenix area. Tallman told his passenger he would follow the coast south to San Diego and then fly eastward to his destination. Approximately 20 minutes after departing Santa Monica, Tallman's light twin flew into the side of a 3,500-foot mountain ridge that had an east/west orientation [located 16 miles from his home field SNA]. The aircraft impacted on a heading of 130' with its wings level and in a slightly nose-down attitude. Ground contact occurred about 3,100 feet msl, straight-on and with no indications that the pilot was incapacitated, that the aircraft was mechanically impaired or that evasive maneuvering had occurred prior to the time the Aztec struck the trees that covered the ridge. According to observers near the accident site, the local visibility was practically nil in heavy rain showers and the ceiling was approximately 800 to 1,000 feet agl. [The weather was unrealistically severe that evening including thunder storms.] --- Sheriff's deputies said the Piper Aztec aircraft went down during the night and was sighted Sunday morning in rugged terrain 50 yards from' the top of a 3,500-foot-high ridge line in the Cleveland National Forest. Tallman had been flying alone. A helicopter airdropped sheriff's dep. Jim Ohr at the scene, one mile from the entrance to Holy Jim Canyon, a few hours later. Ohr said there was massive damage to the right side and front of the plane, "possibly like he was making a left turn in the last minute. It looked like it plowed into the cliff." Tallman was found in the cockpit, with the seat belt On. The emergency locator transmitter was still sending out signals. Ohr said there was considerable turbulence over the mountain. [OC Sheriff: 714 647000, 550 N. Flower St. Santa Ana, CA 92703] --- Keith McGuire, a National Transportation Safety Board investigator assigned to the Oakland office Keith McGuire [ISASI '99 TECHNICAL COMMITTE,ALASKA REGIONAL CHAPTER; NTSB Northwest Region, Rm. 201, 19518 Pacific Hwy. S., Seattle, WA 98188 Regional Director], a National Transportation Safety Board investigator assigned to the Oakland office,said: Reconstructing Tallman's last days, McGuire said the flier had left Santa Monica Airport Friday, April 14, with a client, British film maker Michael Wilson. The two flew along the Sierra Nevada Mountains looking for film locations, then landed in San Francisco where they spent the night. McGuire said both men retired relatively early. They left San Francisco Saturday and flew back to Santa Monica, arriving there at 2:32 p.m. Tallman dropped Wilson off and told him that he was going to fly to Phoenix on personal business before returning to Orange County. After refueling, he left Santa Monica at 2:54 p.m. the time of his List radio contact Twenty minutes later, at 3:14 p.m., his plane hit the 3,100-foot mark of the 3,500-foot ridge just four miles south of Santiago Peak. Tallman was killed just two days before his 59th birthday. When search teams arrived at the brush-covered crash site, they found his body still strapped into the seat of his plane. He had died instantly. |

![]() Well, let's get this out of the way, then. I regularly exceed 30 degrees of pitch in my US-registered aircraft, despite the airplane not being certified in the aerobatic category. Ron, of all people who should know the difference between certificated and certified... My 25-year-old airplane has never undergone an annual inspection. Nor has any experimental aircraft. A once-a-year CONDITION inspection though. I haven't held a medical for about four years, yet I hold a Private Pilot license and fly my N-numbered aircraft regularly. Nor do you need a medical to fly a Light Sport Aircraft, which the FlyBaby certainly is, only a LSA pilot OR HIGHER, which a PPC certainly is.. Being a homebuilt and certificated as such, it HAS to have an N number. Sheesh, you kids. Jim I'll just sit here and wait for the subpoenas and insurance cancellations, then.... Ron Wanttaja |

I could be wrong about that. No, you are undoubtedly right. But there is no such thing as being "certified for 60 degree pitch." The manufacturer can place any warning they wish in the manual, but that's not the same as certification. The airplane is certified in the normal (or utility) category, in the aerobatic category. But this is a *G* limit, not an overt certification limit on bank or pitch angle. If Mooney said the limits are 59 degrees bank and 29 degrees pitch, that STILL wouldn't make it a "certification" limit. From what I can tell, Part 91's only comment about aerobatics is that you have to wear a 'chute...it doesn't seem to care about the certification category of the aircraft. The 91.13 catch-all undoubtedly works, though. As for practice of these manouvers? Do whatever you like. Probably it would not be wise to post here, though, except as a hypothetical question. There's nothing like a written record to influence courts or insurance companies. Well, let's get this out of the way, then. I regularly exceed 30 degrees of pitch in my US-registered aircraft, despite the airplane not being certified in the aerobatic category.

Ron Wanttaja Actually, this explains a lot that had been made a little confusing by some of the discussions which I had heard. In other words, just as a type certif ied aircraft which falls within the LSA limitations of weight, speed and configuration; the same is true for an amateur built experimental with the appropriate operating limitations. That leaves one question about which I am still curious. Do you happen to know what pilot rating and medical certification requirements would exist for the initial pilot of a new amateur built experimental (or a new design) expected to comply with the LSA definitions.

Unfortunately after I look left over the wing to line up with the entry point and initiate first pitch/bank, I'm then at the 90* point and still too fast..... Advice please. Thanks, Dick Why would anyone want to do a lazy-8 once they've completed their commercial? I can understand doing an "8's on" (as a matter of fact, I do them all the time), or a chandelle, but a lazy-8?- Hide quoted text - Lazy 8 is one of the few maneuvers that is challenging, yet graceful and relaxing. You can climb to a high altitude into smooth air, sit back, take a deep breath. The maneuver is very demanding yet it won't make you sweat or grip the yoke tight. Almost every time I fly solo (which is not too often because most of my flights are with pax or students), I do a few. But I don't do 8's-on pylons because I consider bouncing at a few hundred feet while looking out for obstacles and traffic is too much sweaty work. |

Do you happen to know what pilot rating and medical certification requirements would exist for the initial pilot of a new amateur built experimental (or a new design) expected to comply with the LSA definitions. The FAA made this a bit more confusing than they had to. A couple years back, they developed a *definition* of a "Light Sport Aircraft," at the same time they developed two new certification categories, both with "Light Sport Aircraft" in the names (Special Light Sport Aircraft and Experimental Light Sport Aircraft). If an airplane meets the Light Sport Aircraft *definition*, then it can be flown by anyone with a Sport Pilot license or higher. If the aircraft meets the *definition*, a person with a Recreational/Private/Commercial/ATP license and a valid Class III medical or higher may fly the airplane. The same individuals may instead use a valid state drivers license in lieu of the standard medical, PROVIDING their last medical "died a natural death" (e.g., just expired rather than getting canceled) and they have not failed an FAA medical since. It's like the "fourth step" in the standard FAA medical. You can fly operations requiring a Class I for six months, then fly in operations only requiring a Class II for the NEXT six months, and finally can execute Private Pilot privileges for the next year. After that you, you can be a "Private Pilot executing Sport Pilot privileges" for as long as you have a driver's license and DON'T flunk an FAA medical. The certification status of the airplane is immaterial...it can be normal category, utility, aerobatic, experimental, limited, etc. If it *meets* the Light Sport Aircraft definition, a Private Pilot can execute Sport Pilot privileges and use a driver's license in lieu of a medical. The specific aircraft certification categories (Special LSA and Experimental LSA) implement simplified processes to gain airworthiness certificates and simplified maintenance requirements.

Only way to do this would be a Hammerhead, and a Hammerhead done perfectly as well :-) Unfortunately after I look left over the wing to line up with the entry point and initiate first pitch/bank, I'm then at the 90* point and still too fast..... Advice please. Thanks, Dick Hi Dick; I won't get into the mechanics on Lazy 8's as there are literally hundreds of competent sources available and I'm sure you have already read them. Procedure is only part of the equation when it comes to doing a good Lazy 8. Contrary to what some might think, doing a good Lazy 8 within specific parameters is actually not as easy as it might seem. In fact, as an aerobatic instructor, I'll have even a competent acro pilot demonstrate a good Lazy 8 to me before moving on into the "good stuff" :-) The key to doing good Lazy 8's is control coordination and feel. You are dealing directly with an ever changing dynamic in a Lazy 8. This means that your aircraft's altitude, attitude, airspeed, and heading are all in constant flux as you execute the maneuver. There's a lot more involved than simply being at the right point in space at the right time, altitude, and angle of bank. All these things are changing as far as control response goes as the maneuver progresses. As airspeed decreases, you will need to alter the angle of bank to compensate. Same for increasing airspeed. All the while this is going on, you have to be watching your heading change along the arc of the maneuver. What I do with acro students having trouble with Lazy 8's is to have them concentrate on doing a good wingover first. This way, they can concentrate on the 90 degree reference point, the 45 degree point and the 135 degree point on one side only at a time. When you can consistantly perform good wingovers to one side, then the other, you should then put them together and do Lazy 8's. Basically, you are dealing with pitch and bank and what you have to do with varying control pressures with BOTH these parameters to achieve the desired result. Try practicing a single wingover to one side. Let the airplane tell you what you are doing wrong. In aerobatics, (yes, I know the definition as relates to Lazy 8's :-) the airplane will teach you every time you try to perform a maneuver what you are doing wrong. What YOU have to do is WATCH for the difference between what you wanted the airplane to do and what it actually did do based on the control input you provided. In a Lazy 8, if you are early or late at a reference point, you are either early or late in pitch or roll. Ask yourself what you have to change in control input; then try it again with that change. Don't overtask on reference points. Learn where you lose and regain your visual cues vs your reference points vs your high or low wing and compensate for that. Basically what you are looking for is smooth fluid unhurried continious control pressures throughout a Lazy 8. As I said, contrary to what some might say, a pilot who can perform a good Lazy 8 is a pilot who has taken the time to become proficient in the basics, and in all of flying, there is nothing more desirable in a pilot then being someone who can execute based on a well rounded comprehension of the basics.
