Boeing Service Bulletin 737-57-1210 rev 2, mandated by Airworthiness Directive
2008-04-21 / FAA-2007-0226, has a compliance period of 20,000 total flight
CYCLES or 7000 cycles after the date on the SB, whichever occurs later.
However, AD 2008-04-21 has a compliance period of 20,000 total flight HOURS or
within 7000 flight cycles from the effective date of the AD, whichever occurs later.
Could you please confirm that the AD limit should read 20,000 total flight HOURS
and not CYCLES, as stated in the Service Bulletin?
