1993-02-28: Luscombe 8A (N2611K) — Ljc Flyers, Inc — Mason City, IA

Mason City, IA, US

On February 28, 1993, a Luscombe 8A (registration N2611K) operated by Ljc Flyers, Inc was involved in an aviation accident near Mason City, IA. Investigators recorded the probable cause as: The student pilot's improper use of brakes during a crosswind landing rollout, which resulted in the airplane nosing over. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A dual student nose-overs a tailwheel aircraft during landing rollout while practicing takeoffs and landings with an instructor in strong crosswind conditions.

What happened

The private pilot was conducting flight training with a certified flight instructor to obtain the necessary endorsement for operating tailwheel-equipped airplanes. The specific maneuver being practiced involved repeated takeoffs and landings. During one of these landing rollouts, environmental conditions presented a challenge; the wind was blowing from 70 degrees left of the runway heading at a speed of 16 knots.

As the aircraft decelerated on the ground, it began to turn into the wind due to the crosswind component. To maintain control of the aircraft's direction, the flight instructor took control of the yoke and rudder pedals. However, while the instructor was managing the flight controls, the dual student applied the brakes. This abrupt braking action caused the aircraft to pitch forward, resulting in a nose-over incident.

The investigation

The physical examination of the aircraft confirmed that the nose gear collapsed or sustained damage consistent with a nose-over event. The sequence of events was determined by analyzing the control inputs and the wind data available at the time of the accident. The crosswind exceeded typical training parameters for unassisted ground handling without careful throttle management.

Findings

Several factors contributed to this accident. The primary cause was the improper application of brakes during a high crosswind landing rollout by the student pilot. The crosswind component required precise rudder and aileron input, which the instructor was providing. The sudden braking disrupted the aerodynamic control surfaces' effectiveness and shifted the weight distribution forward too aggressively. Additionally, the lack of coordination between the student's braking and the instructor's steering inputs led to the loss of directional control.

Safety message

Pilots practicing tailwheel operations must understand that braking during crosswind landings can be dangerous if not coordinated with the flight instructor. Proper technique involves using differential braking or minimal brake application while maintaining forward pressure on the elevator to keep the nose wheel off the ground until the aircraft is fully under control and the wind component is neutralized.

Probable cause

The student pilot's improper use of brakes during a crosswind landing rollout, which resulted in the airplane nosing over.
