PURPOSE: As indicated in the attached Hartzell Service Bulletin, it has been determined that an incompatibility exists between the "0" rings used in certain constant speed propeller hubs and multigrade engine oil. This incompatability could result in "0" ring deterioration and loss of propeller pitch control. The above listed aircraft have, either as standard or optional equipment, Hartzell constant speed propellers which may be affected by the subject Service Bulletin. Piper considers it mandatory that until Hartzell S.B. 1428 has been accomplished or confirmed, multigrade oil not be used. INSTRUCTIONS: 1. Using the attached aircraft/propeller model and propeller serial number list, verify through the appropriate aircraft paperwork if propeller(s) are affected. NOTE: Any propeller serial number (hub number) below those listed are affected by this Service Bulletin. If propeller(s) have been overhauled subsequent to August 31, 1983, compliance with Hartzell Service Bulletin No. 142B or Hartzell Service Letter No. 148A should have been accomplished, verifiable by entry on the "Servicable" or "Return to Service" tag, or verification may be obtained from the overhaul facility. I SERVICE BULLETIN NO. 805A PAGE 3 OF 3 2. Until compliance with Hartzell Service Bulletin No. 142B has been verified, fabricate and install, in close proximity to the oil filler in full view, a placard worded as follows: Use of Multigrade oil is prohibited. Refer to Hartzell S.B. 142B. 3. Maintain this Service Bulletin along with Hartzell Service Bulletin 142B with the aircraft paperwork until propeller overhaul is accomplished and compliance with Hartzell S.B. 142B is verified. 4. Make appropriate logbook entry of compliance with this Service Bulletin. MATERIAL REQUIRED: Not applicable. AVAILABILITY OF PARTS: Not applicable. EFFECTIVITY DATE: This Service Bulletin is effective upon receipt. SUMMARY: Please contact your Piper Field Service Facility to make arrangements for compliance with this Service Bulletin. NOTE: If you are no longer in possession of this aircraft, please forward this information to the present owner.

Example: HC-C2YK-lBF/F7666A-2 DISCUSSION: As the accumulation of service hours increase on Hartzell propellers, there may be a number of conditions which may contribute to an oil leak. Field experience has shown that one of these conditions is the use of multigrade oils. Oil leaks attributable to multigrade oils, which have superior flow characteristics at lower temperatures tend to appear earlier in operation. This may lead to sluggish operation in pitch change and or external indications of oil leakage. Consideration when defining oil leaks are technique of assembly and wear tolerences. On 31 August 1983, Service Letter No. 148 was published. At that time an "0" ring was introduced which is compatible for use with any known reciprocating aircraft piston engine. (over) Page 1 SERVICE BULLETIN NO. 142B (CONTINUED) ACTION: . . . 11 NOVEMBER 1985 Should the conditions described in the proceeding discussion exist, be completed. we recommend the following action A. It is recommended that all non-color coded O'rings be replaced at next overhaul or prior to that time should any propeller operational conditions be suspect or an oil leak appears. B. For those aircraft with engine and propellers being operated with multigrade oils we recommend that the non-color coded O'ring be replaced at the operators earliest convenience. Sluggish or unusual propeller operation is a prime indication of oil leakage. Any evidence of the above conditions should be thoroughly evaluated, and, if necessary, immediate disassembly and change to the latest style "0" rings. This disassembly and change must be accomplished by a qualified propeller repair person. Operators should check with the last overhaul agency to determine if "0" rings of the new compound were installed in the propeller(s). The latest color coded piston and pitch change rod "0" rings are identified in Service Letter No. 148A. As Hartzell no longer stocks the old "0" ring compound (nor do Hartzell distributors), this problem will be alleviated at next overhaul. It is NOT advisable for propellers operating with factory installed "0" rings prior to 31 August 1983, to be operated with multigrade oils. PUBLICATIONS AFFECTED: This information is now considered part of overhaul manuals No. 113-t ) and No. 117-( ). Page 2
