A couple of intriguing details to note about compliance times in Table 1 of new MOM (5 Nov).
1. If aircraft is BBJ with "Lower Cabin Altitude" STC ie higher pressure differential, then threshold for initial inspection is halved and repeat intervals are cut by 25%. That's drastic and suggests pressure loads were not well modelled in test or analysis.
2. If I'm reading MOM correctly, initial inspection interval after fork replacement is only 3500 flight cycles. Inspections don't start again from scratch.
