REGULATORY TEXT:  
75-17-03 HANDLEY PAGE (SCOTTISH AVIATION, LTD.): Amendment 39-2305. Applies to Jetstream Model HP-137 Mark I airplanes that do not have Handley Page Modification No. 1219 incorporated.

Compliance is required as indicated.

To provide for adequate depth of engagement of wing-fuselage fittings accomplish the following:

(a) For Jetstream airplanes Serial Numbers 213, 216, 217, 218, 220, 221, 224, 237, 238, and 246, within the next 100 hours' time in service after the effective date of this AD or, prior to the accumulation of a total of 2,500 landings, whichever occurs later, unless already accomplished, comply with paragraph (c) of this AD.

(b) For all other airplanes, within the next 100 hours' time in service after the effective date of this AD, unless already accomplished, radiographically inspect spigots, P/N 13781B-5, for depth of engagement of the spigot in its housing in accordance with paragraph 2 (2) of Handley Page Jetstream Service Bulletin No. 7/1, Issue No. 3, dated February 1970, or an FAA-approved equivalent.

(1) If the spigot is found during the inspection required by this paragraph to be recessed in its housing by an amount more than 0.26 inches, before further flight, except that the airplane may be flown in accordance with FAR 21.197 to a base where this work can be performed, comply with paragraph (c) of this AD.

(2) If the spigot is found during the inspection required by this paragraph to be recessed in its housing by an amount of 0.26 inches or less, but greater than 0.20 inches, before the accumulation of a total of 2,500 landings, comply with paragraph (c) of this AD.

(c) Replace affected spigots by accomplishing one of the following:

(1) Install a longer spigot, P/N 13781B-7.

(2) Install a new spigot of the same part number that is shown by radiographic inspection performed in accordance with paragraph 2 (2) of Handley Page Jetstream Service Bulletin No. 7/1, Issue No. 3, dated February 1970, or an FAA-approved equivalent to be recessed in its housing by an amount not exceeding 0.26 inches, and comply with paragraph (d) of this AD, as applicable.

(d) For replacement spigots, P/N 13781B-5, that are found during an inspection required by paragraph (c) of this AD to be recessed by an amount of 0.26 inches or less but exceeding 0.20 inches, before the accumulation of 2,500 landings on the replacement spigot, comply with paragraph (c) of this AD.

(e) For the purpose of complying with this AD, and subject to acceptance by the assigned FAA Maintenance Inspector, the number of landings may be established by dividing each airplane's hours' time in service by the operator's fleet average flight time from takeoff to landing for the Model HP137 Jetstream airplane.

This amendment becomes effective September 1, 1975.
