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

(c) What problem does this AD address? The actions specified by this AD are intended to correct the installation of rivets in the left-hand and right-hand nacelle and spar assembly. These rivets must be present and have correct dimensions in order to prevent reduced structural integrity, which could result in structural failure and possible loss of control of the airplane.

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

Actions	Compliance	Procedures
(1) Insert Raytheon Temporary Changes TC3 (Log of Temporary Changes) into the Limitations Section of the Pilot's Operating Handbook (POH).	Within the next 10 hours time-in-service (TIS) after June 21, 2002 (the effective date of this AD) until compliance with paragraphs (d)(2) and (d)(3) of this AD, unless already accomplished.	Anyone who holds at least a private pilot certificate, as authorized by Section 43.7 of the Federal Aviation Regulations (14 CFR 43.7), may incorporate the pilot's operating handbook (POH) revision required by this AD. You must make an entry into the aircraft records that shows compliance with this AD, in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).
(2) Inspect the left-hand (LH) and right-hand (RH) nacelle and spar assembly for the existence of rivets and installed rivets that are the wrong size and/or type.	Within the next 400 hours time-in-service (TIS) or within 12 calendar months after June 21, 2002 (the effective date of this AD), whichever occurs first, unless already accomplished.	In accordance with the Accomplishment Instructions section of Raytheon Mandatory Service Bulletin SB 54-3308, Issued: October, 2000, and the applicable maintenance manual.

If serious structural damage occurred, contact Raytheon Technical Support for assistance.

(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 2: 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 Steve Potter, Aerospace Engineer, FAA, Wichita Aircraft Certification Office, 1801 Airport Road, Mid-Continent Airport, Wichita, Kansas 67209; telephone: (316) 946-4124; facsimile: (316) 946-4407.
