Aged Aircraft Program II Cessna 152

1. Cessna 152 Manual is revised by (TEMPORARY REVISION NUMBER 5)                                              REASON FOR TEMPORARY REVISION                            1. To add the Supplemental Inspection Documents (SIDs) Information.                            2. To add the Corrosion Prevention and Control Program (CPCP)                             3. To add Control Cable Inspection Information. 2.  CORROSION PREVENTION AND CONTROL PROGRAM (CPCP)                         As the airplane ages, corrosion occurs more often, while, at the same time, other types of damage such as fatigue cracks occur. Corrosion can cause damage to the airplane's structural integrity and if it is not controlled, the airframe will carry less load than what is necessary for continued airworthiness.                      To help prevent this, Cessna started a Corrosion Prevention and Control Program (CPCP). A CPCP is a system to control the corrosion in the airplane's primary structure. It is no

Line Maintenance Outsourcing

Line maintenance is seeing growth as more airlines, struggling with high fuel prices, see this as another area they no longer need in-house. New generation aircraft need outside maintenance specialists who can focus on high-tech entertainment systems, seating, galleys and lavatories. The one qualification to this is the retirement of older aircraft, with replacement models that have longer specified intervals between inspections. As well as the high tech end, outsourced work will include cabin interiors, which is comparatively low-tech. When you consider repairing an armrest on a seat, for example, that is better outsourced, freeing up skilled mechanics for skilled activities. Long-haul, widebody aircraft, operators offering a high degree of premium class services,legacy carriers, which typically operate large aircraft on long international flights, will start to shift more of their line work to third-party vendors. Line work has not been heavily outsourced to date, but overnight c

Line maintenance

Any work at outstations of an air carrier must be performed by approved maintenance organisations. A carrier is encouraged to apply for outstation line maintenance approval based on management by its main base. Equally, the maintenance organisation of a carrier is regarded as an independent organisation when it performs this work on aircraft that are not its own.   General servicing work is not regarded as line maintenance. Self-handling or entrusting to another company by agreement, the carrier submits application to its local civil aviation management organisation for line maintenance approval at outstations for specific aircraft under its maintenance agreement.            A maintenance organisation takes full responsibility for compliance between maintenance at outstations and 145 requirements to the approved standards.  Airworthiness documentation provided by the aircraft manufacturer must be available onsite at outstations. Line Maintenance agreements If a carrier's maint

MEL - Use with Inoperative Equipment

Image
                     CAR requires that all aircraft instruments and installed equipment be operative prior to each departure. It is allowed operations with inoperative equipment determined to be nonessential for safe flight.      The deferral provision of  is widely used by most pilot/operators. Its popularity is due to simplicity and minimal paperwork. When inoperative equipment is found during preflight or prior to departure, the decision should be to cancel the flight, obtain maintenance prior to flight, or to defer the item or equipment.                      Maintenance deferrals are not used for inflight discrepancies. The manufacturer’s AFM/POH procedures are to be used in those situations. The discussion that follows assumes that the pilot wishes to defer maintenance that would ordinarily be required prior to flight.                   Using the deferral provision, the pilot determines whether the inoperative equipment is required by type design,CAR, or ADs. If the inoper

Minimum Equipment Lists MEL

Image
Minimum Equipment Lists (MEL) and Operations With Inoperative Equipment The FAA has developed master minimum equipment lists (MMELs) for aircraft. The operator is required to develops operations and maintenance (O&M) procedures from the MMEL. This MMEL with O&M procedures now becomes the operator’s MEL. The MEL, LOA, preamble, and procedures document developed by the operator must be on board the aircraft when it is operated. The DGCA considers an approved MEL to be a supplemental type certificate (STC) issued to an aircraft by serial number and registration number. It, therefore, becomes the authority to operate that aircraft in a condition other than originally type certificated. With an approved MEL, if the position lights were discovered inoperative prior to a daytime flight, the pilot would make an entry in the maintenance record or discrepancy record provided for that purpose. The item is then either repaired or deferred in accordance with the MEL. Upon confirming tha

Critical and Flight Safety Sensitive Task - Responsibilities

          "Who is responsible to identify tasks requiring independent inspection and to ensure that such independent inspections are carried out?  Is it the person or organisation carrying out maintenance or is it the person or organisation who accomplishes the tasks associated with continuing airworthiness?" From the regulatory point of view there is no clear explanation which defines the responsibility. 145.A.65(b)3 requires a procedure regarding critical tasks. But a critical task according to that explanation does not require an independent inspection. M.A.402(a) requires that an independent inspection shall be carried out after any flight safety sensitive maintenance task.                 But, who is responsible to classify a task as "critical" or as "flight safety sensitive"? Is that really only the person or organisation that carries out maintenance? The responsibility must be shared. Shared between the person or organisation carrying out the mai

FOD - Foreign Object Damage or Debries

                 What is "Foreign Object Debris"? "Foreign Object Debris" is anything that potentially impairs the aircraft’s ability to fly. This may include tools, nuts, bolts, caps, paper, vehicles, people, construction material, packaging, plastic bags, dogs, cats, birds, pencils, phones, books, rocks, pavement pieces, aluminium cans, etc. A "Foreign Object Debris" can be all kinds of objects like these: What can be the consequences of "Foreign Object Debris"?                     "Foreign Object Debris" in the wrong place can create a potential safety problem.                           Or, in other words:  "Foreign Object Debris“ => "Foreign Object Damage" What might be consequences of "Foreign Object Damage"?                       Accident How can we prevent "Foreign Object Damage"?  Most FOD can be attributed to poor housekeeping, facilities deterioration, improper maintenance o

Fuel tank Explosion

           TAE Aviation was fined after it admitted to failing to provide a safe workplace  to a man injured when the fuel tank of a Cessna twin-engine plane exploded in a  hangar .                 Technician sustained minor burns to his  face and lacerations in the blast.  Technician was "relatively fortunate" not  to have been seriously injured through the company's failure to properly drain the  fuel tank in the wing of the plane before repairs on the wing of the plan began. He was exposed to an explosive force, of sufficient intensity to deform metal and  break an arm bone, and with the potential to cause shards of metal to fly off . TAE Systems was charged following a Safework SA investigation and pleaded guilty  to breaching the Occupational Health, Safety and Welfare Act.  TAE had taken an "unacceptably casual attitude" in preparing the  aircraft to be worked upon and had relied on a 1976 Cessna manual and the individual   discretion and judgment of vari

Preventive Maintenance - Battery

  “ Preventive maintenance  means simple or minor preservation operations and the replacement of small standard parts not involving complex assembly operations.” This definition has been tweaked a bit to enable pilots to perform certain functions on their aircraft and the guidelines are presented in Federal Aviation Regulation (FAR) 43.3. Privileges for pilots include tasks such as troubleshooting and repairing landing light wiring circuits but do not include position and panel lights or similar systems that may be more complex. For those not well versed in the art of aircraft repair, words of caution: lack of knowledge may end up costing more in the long run. Replacing and servicing batteries Replacing and servicing batteries is another area where frequent attention can prevent missed trips and is suitable for pilots to accomplish. When replacing any aircraft’s battery, use only one approved for that make and model; plus preventive maintenance does include adding water and top

Preventing Aircraft Corrosion

   After aircraft metal is manufactured, it is immediately protected with corrosion resistant alloy and coated with various metals, paints, and chemical conversions.         Further it requires  continual inspections  and preventative maintenance to keep the aircraft metal from corroding and needing to be replaced.        The most important means for preventing corrosion is to keep aircraft free of moisture.        A thorough rinsing and cleaning of aircraft will remove salt and other corrosive agents. Exposed areas such as the landing gear and cooling vents need extra attention, as well as any other joints, gaps, and hinges where debris collects.     Chipped or delaminating paint needs to be properly striped or sanded and re-painted.        Industrial-grade protectants and lubricants help seal the metal against moisture, and need to be periodically applied to aircraft.          During severe weather or wet conditions, aircraft should be covered and sheltered. It is important to keep

Preventive Maintenance - Guidelines III

25. Cleaning of balloon burner pilot and main nozzles in accordance with the balloon manufacturer’s instructions. Comply with manufacturer’s recommendations. 26. Replacement or adjustment of nonstructural standard fasteners incidental to operations. You are permitted to remove and replace nonstructural standard fasteners, which also includes the removal and replacement of screws or rivets used to attach fasteners. Remember that you must use the approved fasteners, screws, and rivets for your airplane. If you are one of those mechanically gifted people, have at it ‘ drive those rivets. But if you like to put a square peg in a round hole, this may be a complex task for you. 27. The interchange of balloon baskets and burners on envelopes when the basket or burner is designated as interchangeable in the balloon type certificate data and the baskets and burners are specifically designed for quick removal and installation. You must comply with type certificate data sheet. 28. The inst
