The pneumatic system which powers flight instruments and/or deice boots on aircraft which fly Instrument Flight Rules (IFR) is critical to the safety of the pilot and the passengers. If any component of the pneumatic system fails during Instrument Meteorological Conditions (IMC) and the pilot is not proficient in using partial panel instruments, the pilot may become spatially disoriented and may not be able to control the aircraft, resulting in loss of life for the pilot and the passengers. Parker/Airborne pneumatic components are not designed to be overhauled or reconditioned, and no parts of any of these components (including the outer housing and any of the internal parts) can be reused. Parker/Airborne has not and does not overhaul or recondition pneumatic components. Parker/Airborne does not supply any parts, drawings, instructions, specifications or approvals for the overhaul or recondition of its pneumatic components. The parts comprising Parker/Airborne air pumps and/or pneumatic components were designed and manufactured with tolerances to specific proprietary dimensions and distinct materials to meet performance specifications. These parts were individually measured, categorized and placed in matched sets to ensure the component meets (Page 1 of 6) Parker/Airborne Division Parker Hannifin Corporation 711 Taylor Street Elyria, Ohio Fax: techhelp@parker.com Website:

13 Service Letter Number: 66 (continued) pneumatic system performance requirement. Therefore, Parker/Airborne parts only precisely fit with other Parker/Airborne parts of the same matched set and manufacture. Overhauled and reconditioned air pumps and/or pneumatic components are not authorized by Parker/Airborne and can include mixed parts from various vintage Parker/Airborne components, parts made by others, and parts from various components with undocumented history and undocumented traceability. Overhauled or reconditioned Parker/Airborne pneumatic components must not be used and can result in the loss or inadequate operation of gyros and deice boot inflation. SAFETY WARNING: FAILURE OF AN OVERHAULED OR RECONDITIONED PARKER/AIRBORNE PNEUMATIC COMPONENT ESPECIALLY WHILE FLYING IN INSTRUMENT METEOROLOGICAL CONDITIONS (IMC) CAN LEAD TO SPATIAL DISORIENTATION OF THE PILOT AND SUBSEQUENT LOSS OF AIRCRAFT CONTROL RESULTING IN DEATH, BODILY INJURY OR PROPERTY DAMAGE. OVERHAULED OR RECONDITIONED PARKER/ AIRBORNE PNEUMATIC COMPONENTS MUST NOT BE USED AND MUST BE REPLACED IMMEDIATELY WITH A NEW COMPONENT. Compliance: Compliance with the following is mandatory. Within the next 30 days, inspect your aircraft for overhauled or reconditioned Parker/Airborne Pneumatic Components. In order to ensure continued compliance with this Service Letter, continue to inspect your aircraft for overhauled or reconditioned Parker/Airborne components during the annual aircraft inspection. If your aircraft s pneumatic system contains an overhauled or reconditioned Parker/Airborne Pneumatic Component, replace the unit with a NEW one before the aircraft is flown IFR. A. How To Identify Overhauled Or Reconditioned Parker/Airborne Air Pumps. The information below should be used as a guide in determining if you have an overhauled or reconditioned Parker/Airborne air pump. Refer to the applicability section on the first page of this Service Letter for applicable Parker/Airborne model numbers. 1. Nameplates Overhaulers, in most cases, remove the Parker/Airborne nameplate and install one of their own design which indicates Manufacturer: Airborne and may or may not identify the overhauler. Parker/Airborne nameplates will always have either an Airborne or Parker Logo. Overhaulers assign their own serial numbers which have a different format than Parker/Airborne. Parker/Airborne serial numbers consist of a combination of numbers and letters. The first numbers (1 through 12) indicate the month of manufacture (January through December). The next or two letters indicate the year of manufacture followed by the unit number. Parker/Airborne example: 11AU123.

17 Service Letter Number: 66 (continued) B. How To Identify Overhauled Or Reconditioned Parker/Airborne Pneumatic System Valves or Check Valve Manifolds The information below should be used as a guide in determining if you have an overhauled or reconditioned Parker/Airborne pneumatic system valve or check valve manifold. Refer to the applicability section on the first page of this Service Letter for applicable Parker/Airborne model numbers. The easiest way to identify if a Parker/Airborne pneumatic system valve or check valve manifold has been overhauled or reconditioned is by examining the rivets used. Based on the overhauled or reconditioned valves and manifolds that Parker/Airborne has examined to date, overhauled or reconditioned units are reassembled with solid rivets. Parker/Airborne only uses tubular rivets on these assemblies. RIVET HEAD VALVE FLANGE VALVE FLANGE RIVET HEAD GASKET OR DIAPHRAGM HOLLOW SOLID GASKET OR DIAPHRAGM Cross-Section Parker/Airborne s Tubular Rivet Cross-Section Overhauler s Solid Rivet Summary: Promptly and regularly inspect your aircraft for overhauled or reconditioned Parker/Airborne pneumatic components. If you determine that your air pump or pneumatic component is an overhauled or reconditioned Parker/Airborne component, then immediately replace it with a new component. If, after following the above component identification methods, you cannot determine whether your Parker/Airborne component has been overhauled, or if you cannot determine the history of the component, then immediately replace it with a new component. Parker/Airborne realizes that owners and operators of aircraft have the choice of purchasing a new or overhauled/reconditioned air pump, pneumatic system valve, and check valve manifold. However, aircraft owners/operators/pilots should be aware of the increased risk of pneumatic system failure when using overhauled or reconditioned Parker/Airborne pneumatic components.
