Unsafe Condition

Fatigue failures of the nose landing gear actuating cylinder attach bolts.

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

Required Actions

Replace the nose landing gear actuating cylinder bolts with new bolts of the same part numbers (P/N 307402, 307403, 307404) or substitute as specified in Lockheed Service Bulletin 49/SB-616. Compliance must be within specified landing or time-in-service intervals.

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

Compliance Time

Within the next 1,000 landings or 1,000 hours' time in service after December 30, 1963, unless already accomplished within the last 5,000 landings or 5,000 hours' time in service. Thereafter, within each 6,000 landings or 6,000 hours' time in service from the last replacement.

REGULATORY TEXT:  
63-25-02 LOCKHEED: Amdt. 651 Part 507 Federal Register November 30, 1963. Applies to All Models 49, 149, 649, 649A, 749, 749A, 1049-54, 1049C, 1049D, 1049E, 1049G, and 1049H Series Aircraft.

Compliance required as indicated.

As a result of several fatigue failures of the nose landing gear actuating cylinder attach bolts, accomplish the following:

(a) For operators maintaining records of landings, within the next 1,000 landings after the effective date of this AD, unless already accomplished within the last 5,000 landings, and thereafter within each 6,000 landings from the last replacement, comply with (c). Where past records of landings are unavailable the number of landings prior to the effective date of this AD may be obtained by substituting one landing for each hour of time in service prior to the effective date of this AD.

(b) For operators not maintaining records of landings, within the next 1,000 hours' time in service after the effective date of this AD, unless already accomplished within the last 5,000 hours' time in service, and thereafter within each 6,000 hours' time in service from the last replacement, comply with (c).

(c) Replace the nose landing gear actuating cylinder bolts as follows:

(1) Replace the two forward bolts, P/N 307403 and P/N 307404, which attach the forward end of the actuating cylinder to the fuselage structure via a universal joint, with new bolts of the same part numbers.

(2) Replace the aft bolt, P/N 307402, which attaches the actuating cylinder rod to the drag strut pivot, with a new bolt of the same part number.

(3) For those aircraft which use P/N 272216-3 and P/N 272238 in lieu of P/N 307402 and P/N 307403, replace these bolts with new bolts of the same part numbers or replace P/N 272216-3 with P/N 307402 and replace P/N 272238 with P/N 307403 in accordance with items 1, 2, 3, 5, 6, and 7 of the section entitled "Description of Change B" of Lockheed Service Bulletin 49/SB-616.

(4) For those aircraft which use P/N 272216-2 in lieu of P/N 307404 replace this bolt with P/N 307404 and accomplish the rework of the section entitled "Description of Change A", Lockheed Service Bulletin 49/SB-616.

This supersedes AD 63-01-02.

This directive effective December 30, 1963.
