- Importance of periodic CPCP revisions in the evaluation and improvement of the programPublication . Lopes, Hugo Samuel Marinho; Silva, Abílio Manuel Pereira da; Gamboa, Pedro VieiraIn the aeronautic sector, corrosion has been a severe and recurrent problem, mostly since the introduction of metals in aircraft structures and components. This type of damage can affect the structure's integrity, putting in question the airworthiness and safety of the aircraft. History shows us numerous, well-documented aviation accidents, where corrosion was a factor that led to a system failure. Even though improvements have been made, over the years, in the design and manufacturing of new aircrafts, including the use of more corrosion-resistant materials, operators should have a good Corrosion Prevention and Control Program (CPCP) in place throughout the life of the aircraft, achieved through the experience obtained by the operator during the operation of the aircraft. This dissertation exposes the importance of periodic revisions of the aircraft’s CPCP in the fight against corrosion. This research comes from the need of a business jet aircraft operator, NetJets Europe, to reduce maintenance costs related to corrosion and improve aircraft availability. In this work, a segmented and efficient methodology for a comprehensive CPCP revision is described, in order to improve the operator’s economic and operational status. A corrosion findings database was created for each NetJets Europe fleet, in order to obtain an overview of the most affected areas. A complementary study was also performed, in terms of maintenance costs and labor hours, with the objective of finding the most critical areas, structures or components, that needed to be selected for extensive root cause analyses. During the root cause analyses, the aircraft manufacturers and Original Equipment Manufacturers (OEMs) were contacted for a better assessment of the problems. The results show the importance of these analyses in order to find the best countermeasures possible, which can reduce maintenance costs and improve aircraft availability, while maintaining or improving the safety level.
