## The airworthiness directive

60-04-02 BOEING: Amdt. 104 Part 507 Federal Register February 20, 1960. Applies to all Model 707 series aircraft. Due to recent failures of the wing foreflaps, the following shall be accomplished: (a) At intervals not to exceed 65 hours' time in service, inspect all foreflaps except the two outboard foreflap sections (P/N's 65-7360-3007 through 65-7360-3010, 65-7360-3023, and 65-7360-3024) on the outboard flaps 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 inboard and outboard end ribs for cracks or other damage. (b) Any 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. (c) The special inspections in (a) 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 Bulletin No. 546 (R-2) dated November 18, 1959, covers criteria on the same subject.)
