Should a W&B list gross weight?

It is: sa703gl. I did locate plenty of planes that had this done, though, which was fun. I found a couple of NTSB reports regarding aircraft that had had this done, which was less fun. - Andrew That modification includes "• STC Paperwork Package with Gross Weight Increase and all FAA Approved Drawings, Instructions, Flight Manual Revisions, etc." I will bet that in there, possible in the AFM revisions, is the "legal" entry of the gross weight increase.

Should a W&B list gross weight?
Here is another one for youse guys..
What requirement is there that mandates a recomputation of the W&B? The below mentioned handbook states a percentage change, but that will calculate to be more than any simple radio change! IIRC, About 1/2 percent of the maximum gross weight. I have stopped putting useful load and gross figures on the weighing data sheets that I sign off. Take for instance, some turbo sytems allow a gross weight increase. Some tip tank systems allow a gross weight increase. Some jet paperwork allows for a gross weight increase. Beechjet 400 can have a 200 pound takeoff weight increase. All it consists of is paperwork. It means another person can be carried. Wanna know how much. A few years ago, $8k. now about $12K. !! How do I know this/ I weigh one and put tdown the max takeoff weight, useful load etc. A few days later the operators called me and asked for a revision of my document. gee whiz Kent Felkins Tulsa Ok s more mentions "Ron Rosenfeld" wrote in message ...

But the document doesn't state the gross weight. The changes were all avionics; no airframe or power plant work was done. So I'd expect the gross weight to remain unchanged from the prior W&B. But does the new W&B need to state the gross weight, even if it is unchanged? If not, do we then need both documents to cover the legalities of documentation in the airplane? Or did the person that wrote the new W&B err? - Andrew The aircraft gross weight, also called maximum weight,is the maximum authorized weight of the aircraft and all of its equipment as specified in the Type Certificate Data Sheets (TCDS) for the aircraft. It is usually listed on the loading graph or chart supplied by the manufacturer, or perhaps elsewhere in the POH/AFM. The FAA publishes a handbook (FAA-H-8083-1) on weight and balance. With regard to GA aircraft, the following seems to pertain: "Weight and Balance Revision Record "Aircraft manufacturers use different formats for their weight and balance data, but Figure 5-2 is typical of a weight and balance revision record. "... "The weight and balance revision sheet should clearly show the revised empty weight, empty weight arm and/or moment index, and the new useful load." HOWEVER, figure 5-2 shows NO sign of an entry of useful load (or maximum weight). It shows the old empty weight of the airplane; the various adjustments for removal and addition of various avionics with regard to weight, arm and moment; and the computed new empty weight, moment and CG of the aircraft. And you were looking for clarity? Good luck. Bottom line -- it's probably not a requirement. And changes in allowable maximum weight should be reflected in the STC data for the modification that allowed that change; and documented according to the requirements in that STC.

I went to the Penn Yan website, and that comment is in the advertising information for the STC. I could not locate the actual STC, though. However, it should be with the paperwork for the aircraft, and the appropriate AFM changes should have been made. Ron (EPM) (N5843Q, Mooney M20E) (CP, ASEL, ASES, IA) |
