(The Fenwal Installations Noted Are Graviner Systems. Some Mark 2 Cartridges Modified to Mark 3 Have "-3" Added to The Number on The Flat Plate, i.e., A-716-3, Etc. This AD Does Not Apply to Mark 3 Cartridges.) Compliance required as indicated. As a result of instances of the igniter wire in extinguisher cartridges becoming corroded in service, the following shall be accomplished: (a) Within the next 275 hours' time in service or the next 60 days, whichever occurs first after effective date of this AD, unless already accomplished within the past 275 hours' time in service or the past 60 days conduct a continuity inspection of the cartridge circuits using a safety ohmmeter which restricts the current used to 13 milliamperes. A resistance reading of between 5 and 6 ohms indicates a serviceable fuse wire. A resistance reading not between 5 and 6 ohms indicates a defective fuse wire. Repetitive inspection of all cartridge circuits shall be accomplished within each succeeding 550 hours' time in service or 120 days, whichever occurs first after the last inspection. (b) Replace defective Mark 2 cartridges with either serviceable Mark 2 cartridges or with Mark 3 cartridges which have an improved fuse wire. If Mark 2 cartridges are installed the repetitive inspection specified in (a) shall be continued. If Mark 3 cartridges are installed the repetitive inspections specified in (a) may be discontinued. (c) Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, International Division, may adjust the repetitive inspection intervals specified in this AD to permit compliance of an established inspection period of the operator if the requestcontains substantiating data to justify the increase for such operator. (Graviner Technical Notice No. 2 covers this subject.) This supersedes AD 61-02-01. This directive effective May 22, 1962.
2019-25-13: The FAA is adopting a new airworthiness directive (AD) for all Engine Alliance (EA) GP7270 and GP7277 model turbofan engines with a certain low-pressure compressor (LPC) 1st-stage fan blade installed.

60-08-05: 60-08-05 WRIGHT: Amdt. 126 Part 507 Federal Register April 9, 1960, as amended by Amendment 39- 1210. Applies to all TC18DA and TC18EA Series Engines. Compliance required as indicated. (a) To insure that the proper PRT cooling shield to wheel lip clearance is retained, this clearance must be checked at the next regular periodic inspection after May 15, 1960, and every 100 hours time in service thereafter. The maximum service limit for this clearance is 0.080 inch with the wheel in the outermost position and must be checked at the four support bolt locations. In addition to this clearance check, the turbine wheel and turbine shaft nut must be checked for security by attempting to wobble these components by hand. Any looseness is an indication that the nut or shaft has been overheated. If this condition is found, the PRT must be removed for overhaul prior to next flight. (b) At the next overhaul of PRT components after May 15, 1960, and every such overhaul thereafter, dimensional control will be maintained such that a maximum of 0.040-inch wheel to cooling shield clearance with the wheel to cooling shield clearance with the wheel in the outermost position will not be exceeded when the components are assembled. (WAD Service Bulletins Nos. TC18-323 and TC18E-140 cover the above items.) (c) To provide an adequate supply of PRT cooling air under critical engine operating conditions, the aircraft in which these engines are operated should not be climbed at air speeds below the all engine en route climb speed as shown in the FAA approved Flight Manual. It is recognized that under certain unusual conditions, this air speed limitation cannot be adhered to and as a result, the PRT units may be subjected to overheat operation. So that appropriate precautionary measures can be taken when such operation is experienced the flight crew must record in the aircraft log whenever the aircraft is operated below the all engine en route climb speed for periodsin excess of three (3) minutes with the engines operating in high impeller gear ratio at or above alternate climb power. When such operation is reported the No. 2 PRT on each engine must be inspected per item (a) at the first stop where adequate maintenance facilities are available. (d) To further insure PRT cooling cap integrity, a cooling shield security check, with flight hood installed, must be accomplished at 50 hours after every inspection required in paragraph (a). This interval should be as close to the mid-periodic inspection point as practical. This check will be accomplished by individually attempting to move both the intermediate and outer cooling shield outlets. Any relative movement will be cause for flight hood removal and further investigation of the condition of the cooling cap and the security of the PRT wheel and shaft nut. (e) Upon submission of substantiating data through an FAA Maintenance Inspector, the Chief, Engineering and Manufacturing Branch, Eastern Region, may adjust the inspection intervals. This supersedes and cancels item (6) of AD 58-13-05. This amendment 39-1210 is effective May 19, 1971.

Compliance required as indicated. As a result of two incidents of front Lord engine mount fatigue failures on units of old design the following must be accomplished: (a) Inspect mounts for cracks particularly in the web and fillet areas upon next arrival at scheduled stop where maintenance facilities are available and repeat this inspection at intervals not to exceed 50 flight hours. Any mounts with cracks must be replaced immediately with LM- 204A-SA5/Lockheed P/N 632182-9. (b) Replace all LM-204A-SA4 mounts with LM-204A-SA5 mounts within 300 flight hours after first inspection required by (a) but not later than March 1, 1960. (c) All spare quick engine change units must be modified to include the new SA5 mounts prior to installation in aircraft. (Lockheed Service Bulletin No. 228 covers thissame subject.) This airworthiness directive sent by telegram to all operators of 188 aircraft on January 11, 1960.
