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.
Yes I noticed that!
Seems the problem is not the pickle fork itself, but the by product of another "error/assumption/calculation" that causes the pickle to crack - and that is a much bigger fix than a fork change/s over the life of the airframe.
