H-90.............................	LL-1 through LL-61.

(b) Who must comply with this AD? Anyone who wishes to operate any of the above airplanes must comply with this AD.

(c) What problem does this AD address? The actions specified by this AD are intended to detect and replace cracked main landing gear torque knees, which could result in failure of the main landing gear with consequent loss of control of the airplane during takeoff, landing, or other ground operations.

(d) What actions must I accomplish to address this problem? To address this problem, you must accomplish the following:

Actions	Compliance	Procedures
(1) Inspect the main landing gear upper torque knee and lower torque knee for fatigue cracks.	Inspect within the next 100 hours time- in-service (TIS) after February 22, 2002 (the effective date of this AD), and thereafter at intervals not to exceed 1,000 hours TIS.	Do the action following the Accomplishment Instructions paragraph of Raytheon Aircraft Mandatory Service Bulletin SB 32-3134, Revision 1, Revised: July 1999, and the applicable airplane maintenance manual.
(2) If fatigue cracks are found in the main landing gear torque knees during any inspection required by this AD, replace the cracked torque knees.	Before further flight after the inspection.	Do the action following the Accomplishment Instructions paragraph of Raytheon Aircraft Recommended Service Bulletin SB 32-3116, Issued: October 1999, and the applicable airplane model maintenance manual.

(3) When both the left and right main landing gear upper and lower torque knees are replaced with new upper torque knees (part number 50-810032-12) and new lower torque knees(part number 50-810295-25), the repetitive inspection requirement of this AD is no longer required.

You may replace all torque knees at any time, except for those torque knees that are found with evidence of fatigue cracks. Such torque knees must be replaced before further flight, as required by paragraph (d)(2) of this AD.

Do the action following the Accomplishment Instructions paragraph of Raytheon Aircraft Recommended Service Bulletin SB 32-3116, Issued: October 1999, and the applicable airplane maintenance manual.

(e) Can I comply with this AD in any other way? You may use an alternative method of compliance or adjust the compliance time if:

(1) Your alternative method of compliance provides an equivalent level of safety; and

(2) The Manager, Wichita Aircraft Certification Office (ACO), approves your alternative. Submit your request through an FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Wichita ACO.

Note: This AD applies to each airplane identified in paragraph (a) of this AD, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (e) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if you have not eliminated the unsafe condition, specific actions you propose to address it.

(f) Where can I get information about any already-approved alternative methods of compliance? Contact Steven E. Potter, Aerospace Engineer, Wichita Aircraft Certification Office, FAA, 1801 Airport Road, Room 100, Wichita, Kansas 67209; telephone: (316) 946-

4124; facsimile: (316) 946-4407.

(g) What if I need to fly the airplane to another location to comply with this AD? The FAA can issue a special flight permit under sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate your airplane to a location where you can accomplish the requirements of this AD.
