Aircraft Maintenance ‘Gripe Sheets’

These aircraft maintenance comments are allegedly from ‘gripe sheets’ or ‘squawk reports’ which contain pilots’ reports of aircraft technical problems and the responses from maintenance engineers. These amusing communications illustrate the implications of using vague language, as well as the age-old potential for conflict and confusion between operational departments and functions, and the long-suffering tolerance of service and maintenance staff in support of operational personnel found in all industries.

The first lines, in the collections below, represent technical problem or defect reported by pilot or crew. The second lines areĀ remedial actions or answers reported by maintenance engineer.
