SOW.pdf

This is a Statement of Work (SOW) for a Technical Variance (TV) related to aircraft engine maintenance for NASA. Following a borescope inspection of a C-20A left engine (Rolls Royce Spey Mk. 511-8, serial number 11265), a 0.041-inch nick was discovered on the Stage 7 high-pressure compressor blade at the leading edge near the tip. The applicable maintenance manual requires removal from service upon detection of this type of damage. The contractor must provide a Technical Variance determination to assess whether continued aircraft operation with the engine remaining on the aircraft is technically supportable, per quotation OSD 70251.

The contract must be awarded by March 10, 2026, with an estimated completion period of 3 days for the Technical Variance analysis. The SOW includes photographic documentation of the identified damage on the compressor blade. The scope of work is limited to the technical feasibility assessment required to support the variance request, with no additional performance obligations specified beyond this analysis.
