Airworthiness Directive 2000-23-16
recurringAirworthiness Directives; Boeing Model 747 Series Airplanes Powered By Pratt & Whitney JT9D-3 and -7 Series Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747 series airplanes. This action requires repetitive inspections and torque checks of the hanger fittings and strut forward bulkhead of the forward engine mount and adjacent support structure, and corrective actions, if necessary. This action also provides for optional terminating action for the repetitive inspections and checks. This action is necessary to detect and correct loose fasteners and associated damage to the hanger fittings and bulkhead of the forward engine mount, which could result in separation of the engine from the airplane.
Which aircraft AD 2000-23-16 applies to
Requires detailed visual inspection and torque check of the hanger fittings and strut forward bulkhead of the forward engine mount, per Boeing Alert Service Bulletin 747-54A2203, dated August 31, 2000, within 60 days of the effective date, with repetitive inspections/checks and corrective actions per Figure 1 of the service bulletin. Specific 747 series/variant not stated in the extracted applicability text.
Whether AD 2000-23-16 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
