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 theeffect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it. Compliance: Required within the next 200 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished. To prevent a loss of vacuum to depressurize the airplane cabin, which could result in personal injury to the door operator; and to prevent malfunction of the de-ice indicator system which could cause the pilot to unnecessarily exit icing conditions, accomplish the following: (a) Inspect for collapse, deformation, and proper routing of the gray, blue, or clear pneumatic pressurization control system tubes and the de-ice indicator pneumatic tubing located forward of the co-pilot's right outboard rudder pedal in accordance with the ACCOMPLISHMENT INSTRUCTIONS section and Figure 1 of the Raytheon Aircraft Company (Raytheon) Mandatory Service Bulletin (SB) No. 2676, Issued: January 1997. (b) If any of this tubing is deformed or collapsed, prior to further flight, replace the damaged section of tube with new nylon tubing, then use aluminum tubing and hose clamps to secure and re-route the tubing at least 8 inches away from the discharge opening of the co-pilot's foot warmer outlet in accordance with the ACCOMPLISHMENT INSTRUCTIONS section and Figure 2 of the Raytheon Mandatory SB No. 2676, Issued: January 1997. (c) If there is no evidence of damage to the tubing, prior to further flight, re-route and secure the tubing as specified in paragraph (b) of this AD in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of the Raytheon Mandatory SB No. 2676, Issued: January 1997. (d) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. (e) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Wichita Aircraft Certification Office. NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from Wichita Aircraft Certification Office. (f) The inspections, modifications, and replacements required by this AD shall be done in accordance Raytheon Aircraft Company Mandatory Service Bulletin No. 2676, Issued: January 1997.
