AD 2005-13-40 Airworthiness Directives; Boeing Model 727 Airplanes, Equipped With an Auxiliary Fuel Tank Having a Fuel Pump Installed
Models named: 727, 727C, 727-100, 727-100C, 727-200, 727-200F series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
(c) This AD applies to Boeing Model 727, 727C, 727-100, 727-100C, 727-200, and 727-200F series airplanes; certificated in any category; equipped with an auxiliary fuel tank having a fuel pump installed. Unsafe Condition (d) This AD was prompted by a design review of the fuel pump installation, which revealed a potential unsafe condition related to the auxiliary fuel tank(s). We are issuing this AD to prevent dry operation of the fuel pumps for the auxiliary fuel tank, which could create a potential ignition source inside the auxiliary fuel tank that could result in a fire or explosion of the auxiliary fuel tank.
Compliance
(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Airplane Flight Manual (AFM) Revision (f) Within 30 days after the effective date of this AD, revise the Limitations section of the Boeing 727 AFM to contain the following information. This may be done by inserting a copy of this AD in the AFM. “Auxiliary Tank Fuel Pumps Auxiliary tank fuel pump switches must be positioned ‘OFF’ unless the auxiliary tank(s) contain fuel. Auxiliary tank(s) fuel pumps must be ‘OFF’ unless personnel are available in the flight deck to monitor low pressure lights. When established in a level attitude at cruise, if the auxiliary tank(s) contain usable fuel and the auxiliary tank(s) pump switches are ‘OFF,’ the auxiliary tank(s) pump switches should be positioned ‘ON’ again. Each auxiliary tank fuel pump switch must be positioned ‘OFF’ without delay, for all conditions including takeoff and climb, when the respective auxiliary tank fuel pump low pressure light illuminates.” Note 1: When text identical to that in paragraph (f) of this AD has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM. Alternative Methods of Compliance (AMOCs) (g) The Manager, Seattle Aircraft Certification Office, FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19. Material Incorporated by Reference (h) None. Issued in Renton, Washington, on June 21, 2005. Ali Bahrami, Manager, Transport Airplane Directorate, Aircraft Certification Service.
