Each operator of an airplane or turbine-powered rotorcraft desiring to establish or change an approved inspection program under paragraph f 4 of this section must submit the program for approval to the local FAA Flight Standards district office having jurisdiction over the area in which the aircraft is based.
The program must be in writing and include at least the following information:. The instructions and procedures must set forth in detail the parts and areas of the airframe, engines, propellers, rotors, and appliances, including survival and emergency equipment required to be inspected.
When an operator changes from one inspection program under paragraph f of this section to another, the time in service, calendar times, or cycles of operation accumulated under the previous program must be applied in determining inspection due times under the new program.
Aircraft Registration. Experimental Amateur Built Certification. The program must be in writing and include at least the following information: 1 Instructions and procedures for the conduct of inspections for the particular make and model airplane or turbine-powered rotorcraft, including necessary tests and checks.

In addition it contains the rules by which the operator is approved to operate with the program to include extensions and variations which must be applied. The MPD should not be considered the final document in determining appropriate maintenance each operator has direct responsibility to decide what maintenance must be performed and when it should be done.
Airworthiness Limitations AL are a regulatory approved means of introducing inspections or maintenance practices to prevent problems with certain systems. Mandatory replacement times, inspection intervals and related inspection procedures for structural safe-life parts are included in the AL document.
In general the documents which are used to support maintenance and trouble shooting or subsequent rectification are:.

In short, unscheduled aircraft inspection refers to any unforeseen maintenance. Unscheduled aircraft inspection can happen after the cabin crew finds a problem with an aircraft during the preflight inspection.
Unscheduled aircraft inspection can occur when a problem is found during the progressive, annual, or hour inspection or after a flight malfunction.
Examples of unscheduled aircraft inspection could be anything from the sheared vacuum pump, low landing gear strut, in-flight issues to a worn tire. High magneto drop during the run-up and rough running engine are leading reasons why unscheduled aircraft inspection takes place.
Upon discovery, the cabin crew should report a potential problem to the technical team and fill out an unplanned inspection request. The aircraft will then be grounded until the technical team repairs the problem and ascertain that the plane is airworthy and ready to be flown.
Unscheduled aircraft inspection can mean trouble for the flight operators, and the technical team has to handle it before the plane is flown.
Unscheduled aircraft inspection can; however, disrupt a flight and call the need for a spare aircraft to replace its scheduled routes. It might be required that the technical team drive or fly to where the malfunctioned aircraft is, or the aircraft be brought to their workshop. Both of these options can be costly and cause delay, but they are worth it. While each flight has to be approved individually, sometimes the technical team can allow a ferry flight under specific conditions.
Aircraft inspection centers have access to all the servicing records of jets and choppers in their fleet. Manufacturers of aircraft usually publish procedures for repairs that specify the required components, operation checks, and time needed once an unscheduled inspection completes. All aircraft inspection centers should have a predetermined team of troubleshooters with vast experience handling different technical cases for quick assembling of information.
If an aircraft is not airworthy, the inspection team will fly or drive to where it is with all the needed equipment for repair. An airline can either have a standing lease agreement with a company with small aircraft that the technical crew can use to fly to where a malfunctioned plane is. Having these small aircraft works well for airports where big airliners often get damaged or break down as they depart a taxiway or runway. Some airports can speed up an unscheduled aircraft inspection by providing quick access to their equipment and facilities.
These facilities can include crash recovery equipment that can lift and move the plane around and airstairs to get off and on an aircraft. Unfortunately, there are no specific standards that an airline can take to be ready for an unscheduled inspection. Instead, the FAA expects all airports to have a continuing airworthiness program and be prepared for any unexpected breakdown. But the FAA has an advisory circular that outlines some guidelines regarding the use of contract maintenance for repairing unexpected breakdowns.
Anyone owning a fleet of aircraft is required by the FAA to outline the procedurals steps to take when directing and controlling an unscheduled aircraft inspection. Short notices for an unscheduled aircraft inspection do not void the responsibility of the aircraft owners to determine whether their inspection service has competent personnel, adequate equipment and facilities, or the manual for the work being done.
The FAA requires that all these determination be made before the aircraft inspection crew starts working on a plane. The determination methods and procedures for unscheduled maintenance should be in the manual of the aircraft manufacturer. No aircraft is safe in the absence of an unscheduled maintenance and inspection program.
