8.
On Condition - Maintenance concept whereby some components of the engine remain in service as long as they appear airworthy at each inspection. The replace-on-condition concept, as opposed to replace after a specified life-limited time interval, is a decision made by authorized individual performing the test.
9.
Time - as used in this manual.
a. Time-in-service for aircraft components is a cumulative total determined by:
(1)
the date the aircraft was licensed, if new, or;
(2)
the date entered in the logbook for replacement / overhaul of the specific component.
— Note — Do not use the date stamped on the individual component, as these dates are typically applied to determine shelf life - i.e. the maximum time allowed from manufacture/assembly/cure until actually installed in an aircraft.
b. Aircraft time, flight hours, or aircraft hours are the “Hobbs Time” shown on, or calculated from, the installed “Hour Meter.”
C. INSPECTION REQUIREMENTS
1.
Annual / 100 Hour Inspection. (See paragraph D.)
Owners/operators may maintain the airplane solely under FAR 91.409 (a) and (b) inspection requirements. The 100 hour inspection cycle is a complete inspection of the airplane and is identical in scope to an annual inspection. The 500 and 1000 hour inspection cycles are extensions of the 100 hour inspection which require a more detailed examination of the airplane, and overhaul or replacement of some major components. Inspections must be accomplished by persons authorized by the FAA.
2.
Progressive Inspection. The Progressive Inspection program was designed to permit the best utilization of the aircraft through the use of a planned inspection schedule. This schedule is prepared in a manual form, which is available from Piper Distributors:
P/N 761-733 for the PA-44-180 / PA-44-180T family of aircraft. Refer to Piper's Customer Service Information Aerofiche P/N 1761-755 for a checklist to ensure obtaining latest issue.
— Note — The 50 Hour Progressive Inspection Manual (P/N 761-733) referenced above is not a stand-alone document. It consitutes a snapshot of the Airworthiness Limitations and Inspection sections of the Instructions for Continued Airworthiness (ICA) and is current only at the time of printing. Use it as follows:
a.
Owners/operators desiring to establish a Part 91 Progressive Inspection Program (PIP) (see 91.409(d)) or a Part 135 Approved Aircraft Inspection Program (AAIP) (see 135.419) should use the appropriate Progressive Inspection Manual as a template for submission to their regional FAA office.
b.
Service centers conducting Event Cycle inspections under a FAA-approved PIP or AAIP can use the appropriate Progressive Inspection Manual as a working check-off list/form, provided they verify its currency against the FAA-approved PIP or AAIP.

3. Overlimits Inspection. Check with the appropriate component manufacturer if the airplane has been operated so that any of its components have exceeded their maximum operational limits. See 5-50-00.
D. ANNUAL / 100 HOUR INSPECTION PROCEDURE
1. Scheduled Maintenance
a. The required periodic inspection procedure is listed in “Scheduled Maintenance Checks,” below. This inspection procedure is broken down into major groups which include Propeller, Engine, Cabin and Cockpit, Fuselage and Empennage, Wing, Landing Gear, Operational Inspection and General. The first column in each group lists the inspection or procedure to be performed. The second column is divided into four sub-columns indicating the required inspection intervals of 50 hours, 100 hours, 500 hours, and 1000 hours. Each inspection or operation is required at each of the inspection intervals indicated by a circle (O). When vendor publications specify times other than those designated in the the various columns, it will be indicated as:
As req'd by Hartzell Svc. Ltr. No. 61
b. Refer to the applicable chapter of this manual for instructions on how to gain access to remove any item that must be removed and is not completely accessible. To help in the performance of periodic inspections, Inspection Report forms are available through Piper Distributors as:
P/N 230-1963 - SEMINOLE (S/N’s 4496001 & up).
