 INTRODUCTION

The Piper Progressive Inspection meets the F.A.A. progressive inspection requirements of the applicable
Federal Aviation Regulations.

FACTS YOU SHOULD KNOW

Every two weeks the Federal Aviation Administration (FAA) publishes Airworthiness Directives (ADs) that
apply to specific groups of aircraft. They are mandatory changes and are to be complied with within a time
limit set by the FAA. When an AD is issued, it is sent to the latest registered owner of the affected aircraft
and also to subscribers of the service. The owner should periodically check with his Piper Service Center or
A&P mechanic to see whether he has the latest issued AD against his airplane.The owner is solely responsi-
ble for keeping up with ADs.

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.

Service Bulletins are of special importance and Piper considers compliance mandatory. These are sent to
the latest registered owners, Piper Service Centers and Corporate Aircraft Centers.

Service Letters deal with product improvements and service hints pertaining to the aircraft. They are sent to
Piper Service Centers and Corporate Aircraft 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.

Service Spares Letters, which are usualIy sent to Piper Service Centers and Corporate Aircraft Centers offer
improved parts, kits and optional equipment which were not available originally and which may be of interest
to the owner.

An owner should periodically check with a Piper Service Center or Corporate Aircraft Centers to find out the
latest information to 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 interested persons such as owners, pilots and mechanics at a nominal
fee, and may be obtained through Piper Service Centers and Corporate Aircraft 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 a
Piper Service Center.

PROCEDURE MANUAL

1 The Piper Progressive lnspection is recommended by Piper Aircraft Corporation and meets the
requirements outlined in the applicable Federal Aviation- Regulations.

1 The purpose of the Piper Progressive inspection is to allow maximum utilization of the aircraft, reduce
maintenance inspection cost, and maintain a maximum standard of continuous airworthiness.

Owners and operators of the Piper Cheyenne are reminded that certain requirements must be met
1 before the Piper Progressive lnspection Procedures can be utilized. These requirements are contained
in the Federal Aviation Regulations Part 43, Maintenance, Preventive Inspection, rebuilding and
alteration, and Part 91, General Operating and Flight Rules,

1 The inspection frequency used in the Piper Progressive Inspection is based on previous Cheyenne
Operating experience. However, adjustments to the inspection intervals can be made only by Piper
Aircraft Corporation.

Discrepancies found during Inspections will be entered on the Discrepancy Record. The person
conducting the lnspection will advise the Owner and/or Operator of the discrepancies found during
the inspection and entered on the Discrepancy Record. Discrepancies which effect the airworthiness
of the airplane will require the necessary corrective action to be accomplished before the airplane is
returned to service.

1 The Piper Progressive Inspection has the following basic features:

1. Piper Progressive inspection

2. The Two -2- Event Inspections
3. The Special Inspections
4. The Operational Inspection
5. The Event Inspection Record and Sign Off Sheet
6. The Progressive Cycle Inspection Record and Sign Off Sheet
7. The Discrepancy Record
8. Service Publication Compliance Record
9. The Federal Aviation Airworthiness Directives Compliance Record
10. The ECR - Equipment Change Record
11. Access Plate and Panel Locations

Interim Revision: March 26, 1997

I I. Piper Progressive Inspection.

2. Event inspections.
Each Event inspection consists of a predetermined number of location inspections BS
indicated on each event sample. The Event inspection is conducted each 100 hours and must be
done in sequence, and recorded on the Event Inspection Record and Sign Off Sheet, which is the
running log or current status of the aircraft inspections.

Late compliance with the Event Inspection interval of 100 hours may b6 extended by not
more than ten (IO) flying hours (10% of Event inspection Interval). This ten (10) percent shall only
be used to return the aircraft back to the maintenance base which is performing the inspection.
The excess time is included in computing the next 100 flying hours of service.

Early compliance can be accomplished at the owner/operator’s discretion for convenience of

scheduling. However, where early compliance is accomplished, the 100 flying hour interval for
the next event inspection will be maintained. _

The Event Inspections are arranged so that the 200 flying hour cycle results in a complete
inspection. When the Two Events are complete and recorded, an entry is made in the Event
Record and Cycle Inspection Record, which are the running logs or current status of the aircraft
inspections.

Each event will be recorded in the Event Inspection Record and Sign Off Sheet.
