FAA Issues Part 135 Runway Obstacle Analysis Reminder
Some operators found lacking in takeoff safety path analysis

The FAA has published Information for Operators (InFO) 23009 to remind Part 135 certificate holders of the “requirements and authorizations necessary to use airport aeronautical data, including runway obstacle analysis products.” Part 135 Subpart I requires operators of large multi-engine transport and commuter-category airplanes to ensure net takeoff flight path obstacle clearance following an engine failure on takeoff.

Agency surveillance has revealed some Part 135 operators are “lacking proper authorization and/or sufficient knowledge, training, and checking on the use of runway obstacle analysis products and one-engine-inoperative (OEI) departure routing/procedures.” The InFO says an acceptable means to meet these requirements is described in FAA Advisory Circular 120-91A.
