Continued evaluation of crankshafts lots with serial numbers (SN's) other than those that were listed in AD 2000-08-51, has detected the same condition in those crankshaft lots. For crankshafts identified in paragraph (a) of this AD, TCM has already determined which engines have a new suspect crankshaft installed and have identified those engines by engine SN. documents in the last year, 274 (2) Any incident during engine operation in which the propeller impacts a solid object that causes a We know of no ADs on TCM engines in this area to muddy the waters, so its the owners decision unless they are operating other than under Part 91, such as Part 135 where compliance with service directives is typically mandatory. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

This repetition of headings to form internal navigation links Russell says, it should be noted that to comply with A.D. note 91-14-22, the engine does not need to be completely disassembled and that access to the accessory gear train can be accomplished, in most cases, with the engine still installed in the aircraft.
