Accident Probes

Convincing the airplane that youve changed your mind and now want to climb-at the best rate, by the way-requires adding power, arresting the descent and beginning a climb, reconfiguring the airplane and ensuring directional control. While the order in which we perform these tasks varies-check your POH/AFM for the details-we still have to fly the airplane as we accomplish them. That means we can be tempted to add full power when doing so is probably not what we want to do.

While in IFR cruise at 4000 feet, the pilot observed the flight director command bars move out of view as the airplane started a gradual descent. When the pilot corrected, the electric trim started to run nose down and the aircrafts descent rate increased. The pilot attempted to disconnect the autopilot and trim with the control switches and the red disconnect switch. None of this had any effect. With the turbulence and conditions, the pilot was unable to reach the autopilot and electric trim circuit breakers. After all other remedial procedures had failed, he shut off the avionics master switch at about 1000 feet and recovered the airplane at about 500 feet.

Upon raising the landing gear after takeoff, the gear motor continued to operate longer than normal, and the pilot heard an abnormal sound toward the end of the sequence. The right main gear was hanging at about a 45-degree angle, and the left main gear was not visible. The pilot completed the appropriate checklists, without change. The pilot declared an emergency and ATC confirmed during a fly-by that the main gear was not extended. During the landing, the nose gear remained extended and the two main gear were retracted. The airplane came to rest on the runway and the passengers egressed without further incident.

Expecting that I had somehow unknowingly blown my check ride, we landed, shut everything down and he informed me I had…well…passed! A bit confused but obviously glad I hadnt actually blown it, I accepted the good news not wishing to open my mouth and undo it, and simply thanked him. I never told my instrument instructor what the examiner had said, only that he passed me.

For a supposedly CAVU day, I was now pointed at a solid cloud bank. I transitioned to instruments while still VFR and entered the clouds continuing toward VOR #3. It was still smooth as I crossed it and adjusted course toward VOR #4. Shortly after crossing VOR #3, there suddenly were a lot of pilots on the frequency asking for course and/or altitude changes to get out of this weather. I was still enjoying a smooth ride.

Engine began running rough in cruise, the pilot diverted and the aircraft was landed without damage. Investigation found the fuel line between the fuel flow transducer and fuel flow divider was loose at the flow divider. Although it seems unlikely, the aircraft operator has to consider the possibility that this fuel line came loose by itself in the five days and 23 hours of flying since the last scheduled inspection….

After recounting some of his adventures as a military pilot, he went on to say, Anyway, during all of this time I always wondered what happened to her. Losing track of her was like losing track of an old friend. I hope she is well. Perhaps by now she has forgiven if not forgotten the times I ran her a little too rich or too lean, smacked that branch with her wingtip, or disparaged her tail number by having it reported to the authorities.

The old stereotype of crop dusters-excuse me, aerial applicators-is that they are scofflaw daredevils, perhaps with behavior issues. That caricature is a relic of the past, when an enterprising farmer would buy a $300 war-surplus Stearman, put a hopper in the front cockpit and fly the plane hard until it broke. It follows that some might think ag pilots are an unlikely source of safety wisdom, and have fallen far behind aviations cutting-edge technology, but the truth is quite different.

One of the oldest jokes in aviation holds that the big fan is there to cool the cockpit: Whenever it stops unexpectedly, the pilot starts to sweat. Every aviator whos had that experience can probably confirm a significant uptick in pulse and respiration. In the best case, thats accompanied by a corresponding intensification of focus, rapid execution of the memory steps of the emergency procedures checklist and efficient assessment of available alternatives. In the worst…well, those pilots arent available for interviews, but tapes of their radio transmissions can make for uncomfortable listening.
