This report addresses the issue of on-wing testing of large turbofan engines used in transport aircraft. The expanded use of installed testing is addressed along with the factors pertinent to the decision of doing on-wing testing. The maintenance capabilities of the operator, environmental concerns, space requirements, and available instrumentation need to be considered carefully. Several aircraft and engine maintenance manuals were reviewed in relation to summarizing the original equipment manufacturer's requirements and precautions for on-wing testing. Asymmetric power limits, exhaust and inlet hazard areas, ice and snow, and cross/tail-wind restrictions are some of the areas of concern. The benefits and drawbacks are outlined along with proposed solutions to anticipated problems.
