Unsafe Condition
Failures of the wing foreflaps due to cracking or damage in the interior web, flanges, cutouts, and skin areas of the original type outboard foreflaps (P/N 65-7360-3007 and 65-7360-3008).
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Conduct daily inspections including visual checks for cracking, borescope inspections of interior web, flanges, and cutouts, and dye checks on skin areas. Replace or repair cracked or damaged foreflaps before next flight. Redesigned foreflaps (P/N 65-7360-3023 and 65-7360-3024) require inspections every 65 hours' time in service unless inertia dampers (P/N 69-11124-1 and 2) are installed.

Compliance Time
Daily inspections must be conducted as specified. Redesigned foreflaps require inspections not to exceed 65 hours' time in service. Repairs or replacements must be done prior to next flight.

Affected Aircraft
All Boeing Model 707 series aircraft with original type outboard foreflaps (P/N 65-7360-3007 and 65-7360-3008) or redesigned type (P/N 65-7360-3023 and 65-7360-3024) on outboard mainflaps.

Applies to all Model 707 series aircraft. Due to recent failures of the wing foreflaps, the following must be accomplished at times indicated: (a) Conduct daily inspection of the original type outboard foreflap, P/N's 65-7360-3007 and 65-7360-3008, on outboard mainflap as follows: (1) Conduct detail visual inspection of foreflaps for any evidence of cracking. (2) By use of borescope or equivalent, inspect interior web, flanges and cutouts on both the inboard and outboard end ribs for cracks or other damage. (3) By means of dye check or equivalent, examine skin areas at ends of reinforcement plate on upper surface. (b) When the original type outboard foreflap on each outboard mainflap has been replaced with the redesigned type, P/N's 65-7360-3023 and 65-7360-3024, the daily inspection, (a) above, may be discontinued. However, the redesigned foreflap must then be inspected at intervals not to exceed 65 hours' time in service as prescribed in (a)(1) and (a)(2) above. (c) Any outboard foreflap showing evidence of cracking or other damage must be replaced or repaired in accordance with FAA approved manufacturer's instructions prior to next flight. (d) The special inspections of the outboard foreflap, P/N's 65-7360-3023 and 65-7360- 3024, prescribed in (b) above may be discontinued when an inertia damper P/N's 69-11124-1 (left wing) and 69-11124-2 (right wing) has been installed on the foreflaps. (Boeing Service Bulletins No. 456 (R-2) dated November 18, 1959, and No. 566 dated August 26, 1959, cover criteria on the same subject.) This supersedes AD 59-25-01. FOOTER:
