Safety Recommendation A-17-007
Details
Synopsis: On May 13, 2014, about 1511 central daylight time, a Beechcraft Beechjet 400A, registration number N412GJ, equipped with two PWC JT15D-5 engines, experienced a fire in the No. 2 (right) engine following a birdstrike during takeoff roll at Sugar Land Regional Airport (SGR), Sugar Land, Texas. The flight crew successfully rejected the takeoff and discharged both fire bottles, which extinguished the fire. During an examination of the airplane, fuel was found leaking from the No. 2 engine cowling and from a puncture in the right wing fuel tank. The No. 2 engine fan blades were all fractured near the root. The No. 2 engine cowling had multiple penetrations and there was evidence of blade fragments impacting the inlet cowl forward of the fan.
Recommendation: TO TRANSPORT CANADA: Require that all JT15D-5 engines installed on Raytheon/Hawker Beechjet 400A airplanes be modified to dampen the rub-induced excitation that can occur between the engine fan and fan case during birdstrike or foreign object ingestion events.

Date: 8/31/2017
Response: We note that TC has met with PWC regarding this recommendation, and that PWC is currently developing a solution to address the issue. TC gave a proposed schedule indicating that the design concept rig test was scheduled to be completed in the second quarter of 2017. Because the letter was dated in the third quarter of 2017, we assume this item has been completed and that PWC remains on schedule to release its final resolution by the end of the second quarter of 2018. Finally, we note that TC may mandate PWC’s solution. Pending PWC’s resolution, and TC mandating this revision, Safety Recommendation A-17-7 is classified OPEN—ACCEPTABLE RESPONSE.
