Service Letter No: 66

Date: January 31, 2007

Subject: Mandatory Inspection and Replacement for Overhauled or Reconditioned Parker/Airborne

Air Pumps, Pneumatic System Valves and Check Valve Manifolds

Applicability:

This Service Letter applies to all aircraft with pneumatic systems powering critical flight instruments (e.g. pneumatic

powered artificial horizon and/or pneumatic powered directional indicator) and/or deice boots. This Service Letter

applies to all Parker/Airborne component model numbers. A list of these model numbers is provided below.

Applicable Parker/Airborne Model Numbers:

Air Pumps:

Any model beginning with 211 through 216, 241 through 242, 441 through 442, 842, 28C214, 28C444, 4A2

or 4A3.

Check Valves, Check Valve Manifolds and Regulator Check Valve Manifolds:

Any model beginning with 1H5, 1H24, 1H37, 2H24 and models 2H3-39 or 2H3-47.

Vacuum Regulators and Pressure Regulators:

Any model number beginning with 2H3 or 2H30.

Pneumatic System Valves:

Any model beginning with 1H27, 1H43, 1H44, 1H47, 1H51, 1H52, 1H53, 2H22, 2H48, 2H59 or 2H86.

Background:

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

Parker/Airborne Division Parker Hannifin Corporation711 Taylor Street Elyria, Ohio 44035 440 284-6215 Fax: 440 284-6208

pneumatic system performance requirement. Therefore, Parker/Airborne parts only precisely fit with otherParker/Airborne parts of the same matched set and manufacture.

Overhauled and reconditioned air pumps and/or pneumatic components are not authorized by Parker/Airborne andcan include mixed parts from various vintage Parker/Airborne components, parts made by others, and parts fromvarious components with undocumented history and undocumented traceability. Overhauled or reconditionedParker/Airborne pneumatic components must not be used and can result in the loss or inadequate operation of gyrosand deice boot inflation.

Compliance:

Compliance with the following is mandatory.

Within the next 30 days, inspect your aircraft for overhauled or reconditioned Parker/Airborne PneumaticComponents. In order to ensure continued compliance with this Service Letter, continue to inspect your aircraft foroverhauled or reconditioned Parker/Airborne components during the annual aircraft inspection. If your aircraft’spneumatic system contains an overhauled or reconditioned Parker/Airborne Pneumatic Component, replace the unitwith 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 reconditionedParker/Airborne air pump. Refer to the applicability section on the first page of this Service Letter forapplicable Parker/Airborne model numbers.

1. Nameplates – Overhaulers, in most cases, remove the Parker/Airborne nameplate and install one oftheir 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 assigntheir own serial numbers which have a different format than Parker/Airborne. Parker/Airborne serialnumbers consist of a combination of numbers and letters. The first numbers (1 through 12) indicate themonth of manufacture (January through December). The next or two letters indicate the year ofmanufacture followed by the unit number.

Parker/Airborne example: 11AU123. Overhauler examples: 38956, 25AK364


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.

B. How To Identify Overhauled Or Reconditioned Parker/Airborne Pneumatic System Valvesor Check Valve Manifolds

The information below should be used as a guide in determining if you have an overhauled or reconditionedParker/Airborne pneumatic system valve or check valve manifold. Refer to the applicability section on thefirst 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 beenoverhauled or reconditioned is by examining the rivets used. Based on the overhauled or reconditionedvalves and manifolds that Parker/Airborne has examined to date, overhauled or reconditioned units arereassembled with “solid” rivets. Parker/Airborne only uses “tubular” rivets on these assemblies.

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/Airbornecomponent, then immediately replace it with a new component. If, after following the above component identificationmethods, you cannot determine whether your Parker/Airborne component has been overhauled, or if you cannotdetermine 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 oroverhauled/reconditioned air pump, pneumatic system valve, and check valve manifold. However, aircraftowners/operators/pilots should be aware of the increased risk of pneumatic system failure when using overhauled orreconditioned Parker/Airborne pneumatic components. An overhauled or reconditioned Parker/Airborne pneumaticcomponent must not be used. Any time a Parker/Airborne pneumatic component is replaced, a new one must beused.

Subject: Pneumatic pump vane inspection with S.M.A.R.T Stick Applicability: This inspection procedure applies to all new FAA PMA approved pneumatic pumps manufactured by Rapco, Inc. that are equipped with a vane wear inspection port. Inspection Compliance: The inspection procedure listed below should be accomplished after 500 hours time in service on all 200 series pumps and after 200 hours time in service on all 400 series pumps. After the initial inspection, the pump should be re-inspected after 100 hours time in service or annually (which ever occurs first). This inspection procedure is recommended to be accomplished in conjunction with a 100 hour or annual inspection. NOTE: No other vane wear measuring devices are approved for use with this inspection procedure. Procedure: NOTE: Before accomplishing this inspection it is important to make sure that the Aircraft Engine Magnetos are in the off position.

1. Remove inspection port cap screw and lock washer. 2. Rotate Propeller by hand while looking into the inspection port with a flashlight. 3. Line up a vane slot with the inspection port. NOTE: If vane slot to inspection port alignment is incorrect it

will result in an incorrect vane wear measurement. 4. Remove the S.M.A.R.T stick wear sleeve from the S.M.A.R.T stick handle and place it on the S.M.A.R.T
