REGULATORY TEXT:  
70-10-07 HAWKER SIDDELEY: Amdt. 39-991. Applies to "Heron" Model DH.114 series 2 airplanes which have not incorporated HSA Modification 1093.

Compliance is required as indicated.

To prevent failure of the nose landing gear locking lever and jack attachment lever, accomplish the following:

(a) Within the next 150 hours' time in service after the effective date of this AD unless already accomplished within the last 150 hours' time in service, and thereafter at intervals not to exceed 300 hours' time in service since the last inspection, visually inspect the nose landing gear locking lever (P/N 4UN.41A) and jack attachment lever (P/N 4UN.323A) for cracks.

(b) If cracks are found during the inspections required by paragraph (a), before further flight, either replace the cracked lever with a serviceable lever of the same part number or comply with paragraph (c).

(c) Unless already accomplished in accordance with paragraph (b), on or before March 1, 1971, replace the nose landing gear locking lever (P/N 4UN.41A) and jack attachment lever (P/N 4UN.323A) with HSA Modification 1093 levers in accordance with Hawker Siddeley Aviation Ltd. Technical News Sheet Heron (114) No. U.13 dated December 8, 1969, or an FAA- approved equivalent.

(d) The inspections required by paragraph (a) may be discontinued following compliance with paragraph (c).

(e) Upon request by the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Aircraft Certification Staff, FAA Europe, Africa, and Middle East Region may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for that operator.

Amendment 39-991 effective June 14, 1970.
This Amendment (39-1062) becomes effective August 11, 1970.
