INTRODUCTION
This section provides general guidelines relating to servicing and maintenance of the Comanche.
Piper Aircraft has from time to time has issued Service Bulletins, Service Letters and Service
Spares Letters relating to the aircraft which have been available from various sources including a
subscription service.
Service Bulletins are of special importance and should be complied with promptly. Service Letters
deal with product improvements and service hints pertaining to the aircraft. Service Spares Letters
offer improved parts, kits and optional equipment that were not available originally, and which
may be of interest to the owner. In addition, numerous STC modifications are available for the
aircraft from independent sources.
A
Service Manual and Parts Catalog are also available from Piper dealers and other sources.
SERIAL NUMBER PLATE
The serial number plate on the early model Comanche 250 is located on the right front floorboard
under the carpet. On later models it in mounted inside the baggage compartment door The serial
number of the plane should always be used when referring to the airplane in service matters.
INSPECTION PERIODS
The
FAA
occasionally publishes Airworthiness Directives that apply to specific groups of aircraft.
When an
AD
is issued, it is sent to the registered owner of the aircraft. The owner is advised to
periodically check with his Piper dealer or
A&P
mechanic to insure that he has all ADS issued
against his aircraft.
One-Hundred Hour Inspections are required by law if the aircraft is used commercially, otherwise
this inspection is left to the discretion of the owner. Details of the inspection are listed in the
inspection report of the Service Manual.
An
Annual Inspection is required once each twelve calendar months to keep the Airworthiness
Certificate in effect. It is the same as a 100 Hour Inspection except that it must be signed by an IA
mechanic or a
GAD0
representative. This inspection is required whether the aircraft is operated
commercially or otherwise.
In place of the 100 Hour and Annual Inspection requirements, an aircraft may be inspected in
accordance with a Progressive Inspection schedule which allows the work to be divided into
-
smaller operations that can be accomplished in shorter time periods thereby allowing maximum
utilization of the aircraft while complying with all
FAA
and factory recommended maintenance
procedures.
