Time Limits/Maintenance Checks
A. General
Piper Aircraft Corporation takes a continuing interest in having the owner get the most efficient use from his airplane and keeping it in the best mechanical condition. Consequently,Piper Aircraft, from time to time, issues service bulletins, service letters and service spares letters relating to the aircraft.
(1)  
Piper Service Bulletins are of special importance and Piper considers compliance mandatory. These are sent to the latest registered owners and Piper Cheyenne Service Centers.

(2)  
Service Letters deal with product improvements and service hints pertaining to the aircraft. They are sent to Piper Cheyenne Service Centers and sometimes directly to owners so they can properly service the aircraft and keep it up to date with the latest changes. Owners should give careful attention to the service letter information.

(3)  
Service spares letters, which are usually sent to Piper Cheyenne Service Centers, offer improved parts, kits and optional equipment which were not available originally and which may be of interest to the owner.

Aircraftoperated for other than normal operation, such as air taxi or operating in extreme climates, may need more frequent inspection to detect wear, corrosion, or lack of lubrication. Under these conditions, inspections should be conducted more frequently, until operators can set their own schedules based on findings.
An owner should periodically check with a Piper Cheyenne Service Center to find out the latest
informationto keep his aircraft up to date.
Piper Aircraft Corporation has a subscription service for the service bulletins, service letters and service spares letters. This service is offered to owners, pilots and mechanics at a nominal fee and may be obtained through Piper Cheyenne Service Centers. Owners residing outside of the United States are urged to subscribe to this service since Piper can seldom otherwise obtain the addresses of foreign owners. Service product support manuals and revisions are available through Piper Cheyenne Service Centers.
The first overhaul or replacement of components shouldbe performed at the given periods. The condition of various components can then be used as criteria for determining subsequent periods applicable to the individual airplane, depending on usage, providing the operator has an approved monitoringsystem. The time periods given for inspections of various components is based on average usage and environmentalconditions.
NOTE: The listed inspection,overhaul and replacementschedules do not guarantee that particular item will reach the listed time without malfunction, as the above stated conditions cannot be controlledby the manufacturer.
