What to do
Operators of affected Boeing 747 models must comply with the inspection and repair requirements as specified in Boeing Alert Requirements Bulletin 747-53A2899 RB, Revision 1, dated April 7, 2020. The effective date for compliance is July 28, 2020. Any repairs must follow FAA-approved methods, and alternative methods of compliance can be requested through the FAA Seattle ACO Branch.
Summary
Correction to Airworthiness Directive 2020-14-02 issued by the Federal Aviation Administration (FAA) affecting all Boeing 747 series airplanes including models 747-100 through 747SP. The directive addresses inspection requirements for the fuselage bulkhead structure at body station 2598 to detect and repair fatigue cracking. This correction fixes previously incorrect AD and amendment numbers published in the original document.
What changed
The correction updates the AD number from the incorrect AD 2020-12-10 to the correct AD 2020-14-02 and changes the amendment number from 39-19919 to 39-21156. No other changes to the inspection requirements or compliance instructions were made. The correction ensures proper identification and referencing of the AD in regulatory materials.
Why it matters
Accurate AD and amendment numbers are critical for operators, maintenance personnel, and regulatory compliance teams to correctly identify and implement required inspections and repairs. This correction prevents confusion with another AD affecting Bell Textron helicopters and ensures that Boeing 747 operators follow the correct directives to maintain structural integrity and flight safety. Proper compliance helps avoid potential structural failures and loss of airplane controllability.
