Applies to Models 707 and 720 Series Aircraft Noted in Boeing Service Bulletin No. 2073(R-1). Compliance required as indicated. Investigation of a recent failure of the nose gear drag brace lock rod upper attachment bolt, which resulted in the affected aircraft landing with the nose gear retracted, indicates that this bolt is susceptible to fatigue failures and requires replacement. (a) Bolt P/N BAC B30ABP6-37 shall be replaced as follows: (1) Bolts having 5,400 or more hours' time in service on the effective date of this AD shall be replaced in accordance with paragraph (3) within 600 hours' time in service after the effective date of this AD. (2) Bolts having less than 5,400 hours' time in service on the effective date of this AD shall be replaced in accordance with paragraph (3) prior to the accumulation of 6,000 hours' time in service. (3) Replace nose gear drag brace lock rod upper attachment bolts P/N BAC B30ABP6-37 with a new bolt of the same part number or with Standard Pressed Steel Company bolt SFH 22-6-35, Voi-Shan Mfg. Co. bolt VS 2545H6F35T, or a bolt approved by the Chief, Aircraft Engineering Division, FAA Western Region. (4) Bolts P/N BAC B30ABP6-37 installed in accordance with (3) shall be repetitively replaced thereafter within each 6,000 hours' time in service from the last replacement unless they are replaced with Standard Pressed Steel Co., bolt SFH 22-6-35, Voi-Shan Mfg. Co. bolt VS 2545H6F35T, or a bolt approved by the Chief, Aircraft Engineering Division, FAA Western Region. (b) Operators who have not kept records of hours' time in service on nose gear drag brace lock rod upper attachment bolts shall substitute airplane hours' time in service in lieu thereof.
