Unsafe Condition

Cracking of frames around the attachment holes of certain support brackets of the air conditioning (A/C) outlet extrusions, which, if not corrected, could lead to a severed frame that, combined with cracking of the skin lap splice above stringer 10, could result in rapid decompression of the airplane.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Conduct a one-time general visual inspection of frames between body station (BS) 360 and BS 907 to determine if certain support brackets of the A/C outlet extrusions are installed. Perform medium- and high-frequency eddy current inspections for cracking of the frames around the attachment holes of the subject brackets. Repair if necessary. Install new, improved fittings for all support brackets of the A/C outlet extrusions between BS 360 and BS 907.
