- History of Flight:
On September 7, 2026, at about 1719 local time, a privately-registered Cessna 172 Skyhawk II, N734ZK, was destroyed when it was involved in an accident at Montgomery-Gibbs Executive Airport (MYF/KMYF), San Diego, California. The flight instructor and student pilot were fatally injured. The local training flight originated from KMYF.
According to flight-tracking history, the airplane was a frequent flyer out of KMYF, flying out on local flights on daily bases.
According to Automatic dependent surveillance-broadcast (ADS-B) data, at 1156 local time, the airplane departed KMYF and headed north to conduct a number of maneuvers before returning to the airport. The airplane conducted two touch-and-go(es) on runway 28L before coming to a stop. The flight lasted 49m.
At 1627, the airplane departed KMYF again and started a series of touch-and-go(es) on runway 28L. The accident occurred during the ninth go-around to runway 28L.
(ADS-B data section will be written soon I promise)
According to Air Traffic Control (ATC) communications, the controller informed N734ZK about traffic on 2 mile final for the parallel runway (28R) and cleared them to land on runway 28L. N734ZK acknowledged the message and stated they were looking for traffic. A few seconds later, N734ZK informed the controller they were going around. The controller told N734ZK to extend upwind and that traffic was 11 o'clock about a mile and a half entering the left downwind for the parallel runway. N734ZK responded that he was extending down upwind. The controller then told N734ZK to use caution because he was drifting to the north because traffic (a citation mustang) was departing in trail to westbound. N734ZK responded that they were correcting to the south. The controller then asked N734ZK to turn crosswind at Cessna for the parallel and "pass off your left". N734ZK responded that they were turning left "crosswind traffic in sight." The controller then said "Cessna 4ZK, and give it to you, Cessna mile ahead of you in the stadium, they're gonna turn base for the parallel number 1, runway 28L, cleared for the option, additional traffic approaching a 1 mile final for the parallel on the other side." N734ZK responded: "Yeah, looking for traffic ahead and you said we're number 1? 4ZK" The controller responded: "4ZK, affirmative, number 1, runway 28L cleared for the option." N734ZK then said: "okay, number 1, 28L, cleared for the option, 4ZK." A few seconds later, the controller said "Cessna 4ZK, on traffic for the parallel for your right." N734ZK responded that traffic was in sight. The controller then started talking to a different airplane and reported that winds were 310 at 17 knots gusting 22 knots. When the controller said this, The pilot of N734ZK said that they were going around. 4 seconds later, an impact sound was heard from N734ZK. The controller then told the other airplane on approach that "they just had an accident" and that the airport will be closed, shortly afterwards there was a 5-second transmission from N734ZK that suggests one of the pilots was screaming. There were no more transmissions from the accident airplane.
Witnesses at the airport stated that the airplane entered a stall/spin during the attempted go-around and struck the ground hard. A post crash fire ensued which prevented witnesses from reaching the occupants. Another witness on site stated: "Student and instructor third attempt at landing 28L, 40ยบ, crosswind 13-16 knots, stall/spin into the hold short line for 28L."
- Pilot Information:
Unknown at this point.
- Airplane Information:
The four-seat, high wing, fixed gear airplane, serial number 17269243, was manufactured in 1977. It was powered by a Lycoming O-320 engine.
According to the Pilot Operating Handbook (POH):
BALKED LANDING
In a balked landing (go-around) climb, reduce the wing flap setting to 20" immediately after full power is applied. If obstacles must be cleared during the go-around climb, reduce the wing flap setting to 10° and maintain a safe airspeed until the obstacles are cleared. Above 3000 feet, lean the mixture to obtain maximum RPM. After clearing any obstacles, the flaps may be retracted as the airplane accelerates to the normal flaps-up climb speed.
MANEUVER LIMITS
NORMAL CATEGORY
This airplane is certificated in both the normal and utility category. The normal category is applicable to aircraft intended for non aerobatic operations. These include any maneuvers incidental to normal flying, stalls (except whip stalls), lazy eights, chandelles, and turns in which the angle of bank is not more than 60°. Aerobatic maneuvers, including spins, are not approved.
The stall speed (CAS) with flaps up, power off was 50 knots, the stall speed (CAS) with flaps down, power off was 44 knots.
Stalls
The stall characteristics are conventional and aural warning is provided by a stall warning horn which sounds between 5 and 10 knots above stall in all configurations.
Power-off stall speeds at maximum weight for both forward and aft c.g. positions are presented in Section 5.
STATL SPEEDS
CONDITIONS:
- Power Off
- 1. Maximum altitude loss during a stall recovery may be as much as 180 feet.
- 2. KIAS values are approximate
- Wreckage and Impact Information:
The airplane came to rest upright on the shortline holding point for runway 28L. There was a post crash fire that consumed the passenger cabin. Both wings and tail remained attached to the airframe, and there was no debris field leading to the main wreckage. The wings and tail showed little to no impact damage. The impact appears consistent with a flat aerodynamic stall/spin with little to no forward airspeed.
