Models named: 757-200, -200CB, -200PF, -300. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all The Boeing Company Model 757-200, -200CB, -200PF, and -300 airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

At the applicable time specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 757-53A0099, dated September 18, 2014, except as required by paragraph (h) of this AD, do detailed and high frequency eddy current inspections for cracking in the fuselage frames in Section 43 at stringer 25, left and right sides, and frames in Section 46 at stringer 24, left and right sides, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 757-53A0099, dated September 18, 2014. (1) If cracking is not found, repeat the inspections at intervals not to exceed 12,000 flight cycles. (2) If any cracking is found, before further flight, repair using a method approved in accordance with the procedures specified in paragraph (i) of this AD. Repeat the inspections at intervals not to exceed 12,000 flight cycles in unrepaired areas.

Unsafe condition

This AD was prompted by a report of cracking in the fuselage frame at Station (STA) 1440, stringer 24L. We are issuing this AD to detect and correct fuselage frame fatigue cracking. Such cracking could result in loss of structural integrity and the inability to sustain loading conditions.

Affected ADs

None.
