SORRY BOB! GUESS MY MEMORY IS FAILING. HOW COULD I FORGET THAT THE
AIRCRAFT THAT DONALD'S PEOPLE WERE USING THAT DAY BACK IN 1989 WAS LEASED
AND NOT OWNED BY TRUMP. I DIDN'T REALIZE THAT THE ACTUAL OWNERSHIP OF THE
AIRCRAFT WAS REALLY THAT CRITICAL TO THIS THREAD ON M/R BLADE FAILURES. ONE
WOULD THINK THAT YOU WOULD HAVE REMEMBERED THE CAUSE OF THE FAILURE AND NOT
HAVE THROWN OUT THAT "FORGING LAP" AS THE CAUSE. huh? JC

IN CLARIFICATION TO THE ABOVE:

THAT WAS NOT "DONALD TRUMP'S AGUSTA THAT WAS LOST IN THE ACCIDENT UP IN
NEW
JERSEY. THAT AIRCRAFT WAS LEASED THAT DAY FROM PARAMOUNT AVIATION. TRUMP
HAD FIVE (5) OF HIS L A R G E HELICOPTERS SITTING IN THE HANGAR ON THE
DAY
THAT THE LEASED AIRCRAFT WAS LOST.

I WAS THE CHIEF INSPECTOR FOR TRUMPS HELICOPTER OPERATIONS AT THE TIME SO
YOU CAN TAKE THIS INFO TO THE BANK. HIS AGUSTA 109 WAS IN MAINTENANCE
THAT
DAY AND WAS UNAVAILABLE. THE BLADE THAT FAILED HAD A "FORGING LAP": LEFT
IN
THE M/R/B SPAR SINCE MANUFACTURE WHICH CREATED A "STRESS RAISER",
EVENTUALLY
A CRACK, AND THE REST IS HISTORY. For the rest of the commenters, now
with
many composite blades out there a better record can probably be expected
although no great inspection methods have yet been developed for
composites.
Metal blades departed aircraft many many times, hence Sikorsky's "BIM"
indicators on the blade roots. Hundreds of thousands od pounds of
centrifugal force and cracked blades will always present a problem, huh?
