Small Hardware Design for Ease of Maintenance and Inspection.
Abstract
The small hardware problems of eight helicopters were reviewed in this program to find common aircraft reliability problems specifically occurring as the result of maintenance actions. Deficiencies of the hardware and the installation were defined. Design principles and concepts to reduce further helicopter reliability and maintainability problems were developed. Airframe hardware and furnishing attachments made up the majority of components studied. Fittings, clamps and other small components in the hydraulic, electrical, pneumatic and fuel systems were also reviewed. Phase I consisted of the indentification of problems by a review of the maintenance data reporting systems and the interrogation of helicopter maintenance personnel and field service representatives. During Phase II, a state-of-the-art hardware survey was conducted to determine if new concept development was required. Candidate replacement hardware was selected for each problem area. In Phase III, present components and candidate replacement components were subjected to a variety of tests, among which were endurance, vibration, environment, maintenance abuse, and static strength tests.
