Gear Down, Stall Horn Sounding: N979BA's Failed Climb-Out at Essex County Airport

A Beechcraft Bonanza pilot flew for thirteen full seconds with the stall warning horn sounding in his ears before the airplane finally stopped flying — climbing out with the landing gear still down, on a departure that never got above 400 feet.

A Climb That Wasn't Climbing

N979BA departed Essex County Airport in Caldwell, New Jersey, on an IFR flight on January 21, 2017, with the pilot alone aboard. Almost immediately, something was visibly wrong: air traffic controllers watching the aircraft's climb saw it barely gaining altitude at all, turning left while remaining well below the altitude it had been assigned. The aircraft topped out around 400 feet above the ground before it began to lose altitude instead of gaining it.

No Mechanical Problem Found

The pilot later reported that the airplane simply would not climb, and that the engine was running normally with no warning lights or alerts. The post-accident investigation backed up half of that account: no evidence of a mechanical or engine failure turned up. What investigators did find was that the landing gear had remained extended and the flaps were still up — a configuration that meaningfully reduces a Bonanza's ability to accelerate and climb. Departing and staying in that configuration, rather than retracting the gear once a positive climb was established, is consistent with an airplane that behaves exactly like the pilot described: sluggish, unable to climb, for reasons that have nothing to do with the engine.

Thirteen Seconds of Warning

ATC's own recordings captured the aircraft's stall warning horn sounding continuously for approximately 13 seconds before impact — a long window, in a cockpit, to not respond to what a stall horn means: lower the nose, or add power, or both, before the wing stops flying. The investigation concluded the airplane likely entered an aerodynamic stall because the pilot did not recognize the warning, or did not respond to it promptly enough, while the angle of attack climbed past the critical point.

Impact

With the stall now developed, the airplane struck the roof of a warehouse before coming down in wooded terrain about half a mile from the runway. A fire after impact destroyed the aircraft. The pilot, the only person aboard, survived but was seriously injured.

What the Investigation Found

The NTSB's probable cause is direct: the pilot's failure to maintain control of the airplane after takeoff resulted in an aerodynamic stall. The gear-down, flaps-up configuration explains why the airplane struggled to climb in the first place; the 13-second stall horn explains that the pilot had a real window to intervene before the stall developed, and did not use it.

This reconstruction was researched from official investigation records where they exist, the original air traffic control recording, and contemporary reporting. The aircraft movement, timeline and written account were assembled independently by Flight Follower. Where an investigation is open or no probable cause has been published, the account says so rather than offering one.
