  • Page 27: Torque Requirements

    PIPER AIRCRAFT PA-28-161 CADET AIRPLANE MAINTENANCE MANUAL 2-8. TORQUE REQUIREMENTS. Proper torque application cannot be overemphasized. Undertorqued assemblies can result in premature failure due to fatigue from uneven loads, as well as causing unnecessary wear of nuts, bolts, and other parts. Overtorqued assemblies can be equally harmful by causing failure of a bolt or nut by overstressing the threaded areas.
  • Page 28 PIPER AIRCRAFT PA-28-161 CADET AIRPLANE MAINTENANCE MANUAL TABLE II-II. RECOMMENDED NUT TORQUES TORQUES: The importance of correct application cannot be overemphasized. Undertorque can result in unnecessary wear of nuts and bolts as well as the parts they are holding together. When insufficient pressures are applied, uneven loads will be transmitted throughout the assembly which may result in excessive wear or premature failure due to fatigue.

  • Page 60 PIPER AIRCRAFT PA-28-161 CADET AIRPLANE MAINTENANCE MANUAL 2-77. INSPECTION. Corrosion should be suspected at every inspection. In trouble areas, the inspection frequency should be increased. In addition to routine inspections: a. Aircraft operating around a marine environment should be given special checks on a weekly basis.
  • Page 61 PIPER AIRCRAFT PA-28-161 CADET AIRPLANE MAINTENANCE MANUAL There are several methods for removing corrosion; chemical treatment; hand sanding with abrasive paper or metal wool; and, mechanical sanding or buffing with abrasive materials or grinding wheels. The method selected depends on the type and extent of the corrosion.
  • Page 62 PIPER AIRCRAFT PA-28-161 CADET AIRPLANE MAINTENANCE MANUAL 2-79. AREAS PRONE TO CORROSION. Certain areas are more prone to corrosion than others. The following list is intended to be a general guide to areas where corrosion is frequently found: a. Areas around steel fasteners are susceptible to corrosion. The paint on these areas cracks which allows moisture to seep in and corrode the under-lying metal.
