EASA AD US-2022-15-09
Fuselage - Fuselage Frame Web - Inspection
Summary
The Federal Aviation Administration's Airworthiness Directive 2022-15-09 supersedes AD 2019-23-06 and applies to certain Boeing 757-200, -200CB, and -300 series airplanes. It mandates inspections of the fuselage frame web fastener holes at body station 1640, including visual and high frequency eddy current (HFEC) inspections, to detect cracks and previous repairs. The directive addresses structural integrity concerns related to cracks that could compromise airplane safety.
What Changed
AD 2022-15-09 reduces the compliance times for certain inspections and on-condition actions originally required by AD 2019-23-06. It also extends the reduced compliance times to airplanes modified with Aviation Partners Boeing winglets and those converted to freighter configurations under specific Supplemental Type Certificates. The directive retains all previous inspection and repair requirements but accelerates the inspection intervals to mitigate risk.
Why It Matters
This directive is critical for aviation professionals as it addresses the risk of undetected cracks leading to structural failure and potential loss of airplane controllability. Operators and maintenance teams must adhere to the shortened inspection intervals to ensure early detection and correction of fuselage frame web cracks. Compliance helps maintain airworthiness and prevents possible explosive decompression due to frame failure.
What To Do
Operators of affected Boeing 757-200, -200CB, and -300 series airplanes must perform the required visual and HFEC inspections of the fuselage frame web fastener holes at STA 1640 within the new, reduced compliance times specified in AD 2022-15-09. On-condition repairs such as fastener installation or hole oversizing must be completed as necessary. The AD is effective August 17, 2022, and comments must be submitted by September 16, 2022.
