The Boeing Company Airplanes
This AD applies to The Boeing Company Model 757-200 airplanes, certificated in any category, modified by supplemental type certificate ST01529SE or ST02278SE.
The FAA is adopting a new airworthiness directive (AD) for The Boeing Company Model 757-200 airplanes modified by particular supplemental type certificates. This AD was prompted by reports of cracking in the structure in and around the lavatory service panel. This AD requires repetitively inspecting the lavatory service panel, access pan, and attaching structure for cracks; reinforcing the attaching structure; and if necessary, replacing the access pan or repairing cracked parts. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with the Accomplishment Instructions of Precision Conversions Service Bulletin PC-757-53A0005, Revision 2, dated May 7, 2024.
(1) Where the table in the “Compliance” paragraph of Precision Conversions Service Bulletin PC-757-53A0005, Revision 2, dated May 7, 2024, refers to the original issue date of this service bulletin, this AD requires using the effective date of this AD.
(2) Where the table in the “Compliance” paragraph of Precision Conversions Service Bulletin PC-757-53A0005, Revision 2, dated May 7, 2024, specifies in Condition 2 Option 1 to repetitively inspect if no cracks are found, this AD does not allow repetitive inspections and requires installing reinforcement within 2,000 flight cycles after the initial inspection in accordance with Paragraph III, Part 3, Reinforcement, of Precision Conversions Service Bulletin PC-757-53A0005, Revision 2, dated May 7, 2024.
(3) Where Precision Conversions Service Bulletin PC-757-53A0005, Revision 2, dated May 7, 2024, specifies contacting Precision Engineering for instructions when specific conditions are found, this AD requires complying with those instructions by using a method approved in accordance with the procedures specified in paragraph (i) of this AD.
