What does the acronym CPCP stand for in Army aviation maintenance?
Answer: Corrosion Prevention and Control Program
CPCP stands for Corrosion Prevention and Control Program, which establishes systematic procedures for preventing and treating corrosion on Army aircraft.
Which type of corrosion most commonly affects aluminum aircraft structures and appears as white or gray powdery deposits?
Answer: Surface corrosion (oxidation)
Surface corrosion (oxidation) is the most common type affecting aluminum, manifesting as white or gray powdery deposits on the metal surface due to reaction with oxygen.
What is galvanic corrosion in the context of Army aircraft maintenance?
Answer: Corrosion that occurs when two dissimilar metals are in contact in the presence of an electrolyte
Galvanic corrosion occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte, causing the less noble metal to corrode preferentially.
Which environmental condition most accelerates corrosion on Army aircraft?
Answer: High humidity and salt-laden air
High humidity combined with salt-laden air, such as in coastal or marine environments, most rapidly accelerates electrochemical corrosion on aircraft metal surfaces.
What is the first step a maintenance technician should take when discovering corrosion on an Army aircraft?
Answer: Document the finding on the appropriate maintenance form
The first step is to document the finding on the appropriate maintenance form (DA Form 2404) so the discrepancy is officially recorded and can be properly assessed and tracked.
Which Army technical manual provides primary guidance on corrosion prevention and control for aviation equipment?
Answer: TM 1-1500-344-23
TM 1-1500-344-23 is the primary Army technical manual providing guidance on painting and corrosion prevention and control procedures for aviation equipment.
What is crevice corrosion and where does it most commonly occur on Army aircraft?
Answer: Corrosion occurring in confined spaces where moisture and contaminants accumulate and cannot drain
Crevice corrosion occurs in confined spaces such as lap joints, under fastener heads, and in gaps where moisture and contaminants accumulate and cannot drain or evaporate.
