Is anyone aware of Slick SB1-98A requiring inspection of the impulse coupling(s) on any 540-XXX5, IO-540-D4A5 as an example? Has anyone had a problem with the rivets on the 5th order counterweight engines?
The engines effected:
The following Lycoming O-540 and IO-540 engines configured with fifth order counterweights:
O-540 A1D5, B2B5, B2C5, E4B5, E4C5, G1A5, G2A5, H2A5
IO-540 AC1A5, C1B5, D4A5, K1A5, K1B5, K1E5, K1G5, K1K5, L1C5, M1C5 AEIO-540 L1B5
TIO-540 AH1A, AJ1A, W2A
The 250 hour impulse coupling inspection must be performed each time the magneto accumulates either 250 hours of operation from the time of the last inspection, field overhaul, or since new or factory rebuilt. See magneto maintenance and overhaul manuals L-1037 or L-1363 for overhaul instructions.
I got this info from the Slick booth at AirVenture
Thanks Gerry
