Aircraft Maintenance Planning & Records

Maintenance Planning plays an essential role in the overall aircraft operation and management. Nowadays, making an aircraft continuously airworthy possess significant challenges to a business in terms of achieving the multiple and sometimes conflicting goals relating to maintenance and operation costs and desired service levels, including safety.

In reality, planning and scheduling of an aircraft maintenance can be demanding, especially in the business aviation sector. It is a fine balance between the aircraft operator`s needs to meet the optimal levels of aircraft performance and MRO/AMO spare-parts availability at decreased downtime. Having so many variables in the equation is calling for not only a reliable computerized maintenance management system but also an experienced team to ensure the most effective way to implement the maintenance program. This is moreover needed considering that studies into industry practices show that only half of the overall maintenance workload come about as a scheduled maintenance, findings during aircraft lay-up are a common reason for the overall delay of the aircraft release to service.

Having a trustworthy partner with the necessary knowledge, skill and experience to act in such a situation is essential in the highly competitive aviation terrain. We in ATTCAMO believe in the high efficiency of our maintenance planning that fits our client`s operation. We have built a network of partners and trusted associates. Our Computerized Maintenance Management System allows us to effectively track, schedule, plan and manage the maintenance activities of our customers` aircraft while our team of highly trained airworthiness engineers is ensuring the updates of the accomplished works.

Our maintenance tracking includes the tracking of:
  • Upcoming maintenance / Service Bulletins /Airworthiness directives as they approach due date
  • Liaison with maintenance facility during a layover
  • Verification of Part 6 (AMO) work package post completion
  • Recommended maintenance actions to stabilize trends

Development of Maintenance Program (MP) & Minimum Equipment List (MEL)

  • MP - Maintenance Program
    We develop Maintenance Program (MP) for commercial and non-commercial operators. And we see to its approval by the authority. The Aircraft Maintenance Program after NCAA approval shall be an approved maintenance program (AMP) for the on-schedule undertaking of all maintenance work. The AMP describes all aircraft-specific maintenance measures, complete with the intervals. The basis is the Maintenance Data (MD / MPD / MRBR etc.) provided by the manufacturer, however, the AMP will also include all the other specific inspections for the serialized aircraft. We are using smart software program in the development of the MP that allows us to create the most comprehensive AMP including all relevant data specified, completely with thresholds, intervals and, if applicable, tolerances. The applicable part numbers are also stated, particularly in the case of service-life-limited components.

  • Minimum Equipment List (MEL)
    The Minimum Equipment List (MEL) is a document approved by the authority and it is required by Aircraft operators (AOC). Each MEL is compiled on the basis of the Master Minimum Equipment List (MMEL). This is a list issued by the manufacturer or the authority, stipulating which aircraft equipment constitutes the minimum that must be available for safe flight. Keeping in mind that any MEL must be tailored to the operation of the aircraft and the requirements of the authority of the country of registration, we take under consideration the special requirements like ETOPS, RVSM and other customer operation criteria when developing the Minimum Equipment List (MEL) for our customers. Since this technical document is the basis for the decision-making process for the certifying staff and/or the pilot’s prior to flight or the crew in the event of a technical defect occurring during a flight, we ensure that the highest safety and professional standards are applied.

Pre-Purchase Inspection & Record Auditing

  • Purchasing an aircraft is a long and complex transaction between two parties. Having a neutral and yet very experienced third party to go through all maintenance related documentation as well as physical examination of the aircraft to ascertain its airworthiness is what is important. The Process of Pre-Purchase (PPI) inspection involves thorough examination of the aircraft conditions, checking for damages and deterioration that may not be easily spotted by the untrained eye. Usually, the extent of Pre-Purchase inspection is determined by the client`s needs in combination with the complexity of the aircraft under inspection. Though it may not be as detailed and complex as an annual inspection, having a comprehensive pre-buy or Pre-purchase inspection is highly recommended to prevent any future heart ache or headache due to unforeseen or hidden troubles. The PPI process can be divided into:

  • PAPERWORK EXAMINATION INCLUDING:

    • Examining the validity of the airworthiness certificate
    • Research into Airworthiness directives
    • Service bulletin compliance
    • Inspection of the logbook for entries suggesting repairs due to an accident or incident
    • Annual inspection entry review
    • Comparison of aircraft serial numbers with the one listed in the logbook
    • Verification of the engine and/or propeller times since major overhaul etc.

  • THE PHYSICAL SURVEY, INSPECTING THE:

    • Fuselage and Empennage
    • Landing Gear
    • Engine and related systems
    • Propeller(s)
    • Wings and Flight controls
    • Cabin Interior and Cockpit
    • Systems basic operation check
    • Any other Specific emphasis on systems and/or structures as required by the particular aircraft.

Once, our team of experienced inspectors completes the above phases, a Pre-purchase inspection report is issued. Aircraft registration also plays a key role in the purchasing process before a Recommendation for import and other relevant documentation is issued.

Consultancy Service

Over the years we have witnessed an increase in the number of aircraft, both new and pre-owned, being imported and registered in Nigeria. The very pro-business corporate taxation system, strong legislative framework and extensive double taxation treaties together with the comprehensive registration possibilities for non-commercial/ commercial air transport makes Nigeria attractive destination for both Aircraft Operators and private owners. The two main processes taking place when aircraft is sold to a buyer in a different country are the export and import. Once the sale is finalized, the aircraft needs to be deregistered from the country of register with an Export Certificate of Airworthiness (C of A). Once the aircraft is delivered and customs-cleared, an Import Airworthiness certificate for the new country of registration needs to be issued verifying the conformity with the local authority`s regulations and requirements. Our professional team has the experience and knowledge to guide and assist you during this transaction and beyond. To ensure that our customers` operation is at its optimum, we offer Independent quality and external audit services. Our team evaluates continuing airworthiness management efficiency and compliance with Nig. CARs. Top on our consultancy agenda are:

  • Aircraft import and export rudiments
  • Build up and operation of a CAMO for Commercial operator
  • Independent quality and external audit
  • Operation of Aircraft Phase In Support
