PART 1

Subtask 521163-220-403-001 - INSPECT THE STUD ASSEMBLIES

A. Do a Detailed Inspection (DI) of the LH and RH fixed fairing door upper and lower

forward attachment stud assemblies for signs of corrosion, wear, fatigue or cracking. Also, check for loose studs. Refer to figures A-UBBAA and A-UFBAA. Report findings to Engineering department.

DEFECTS WERE FOUND IN LH SIDE YES NOT

DEFECTS WERE FOUND IN RH SIDE YES NOT

If there are defects, perform Part 2 of this E.O. IMPORTANT: In case corrosion is found on any MLG fixed fairing forward attachment

stud assembly (upper, lower, LH or RH), but the corroded stud is not loose, within 4 months after finding corrosion and, thereafter, at intervals not exceeding 4 months, accomplish a DETAILED INSPECTION of the forward stud assembly of the affected (RH or LH) MLG in accordance with the instructions of this Engineering Order, instead of replacement of the LH and RH MLG door upper and lower forward attachment studs.

If no defects were found, follow with next step.

I

B. If there are no findings, do the inspection again in accordance with Accomplishment

Timescales. Perform Subtask 521163-942-401-001 - CLOSE-UP
