Time life components

[seneca2e]

Are components like the transmission, etc which are listed on the type certificate data sheet as time life items at 3250 hours just scrap when they reach that time in service or has Brantly authorized continued service as long as the 1200 hour/600 hours inspections/overhauls are done?

I doubt many of these transmission get scrapped as a practical matter but it's a valid question nonetheless.

I only know of a few ships that are close to 3250. Correct answer, the way I understand it, is... at 3250, the MRGB, T/R Intermediate and Main Gearboxes, and the 108-33 T/R Drive Shaft Extension, ALL TURN INTO A PUMPKIN AT MIDNIGHT!!!

The two ships I know of that are within 200 hrs of 3250, already have a MRGB with time left on it, sittin' on the shelf waiting.

There are those who interpret the Type certificate that only the CASE times out, but does that make common sense?
If a Brantly, heaven forbid, was to go down in an area crowded with hundreds of trial lawyers, and kill a handful of them...
...and if the NTSB/FAA found the transmission case S/N had 1500 hours TT, and The main rotor mast S/N had 3201 hours TT????????

What do you think?

Do you think your insurance underwriter (that's who really matters) would BLESS that newer-cased timed-out-gears MRGB?
