N5110R

On June 21, 1998, at 0945 central daylight time, a Beech B19 airplane, N5110R, was substantially damaged following a loss of control while landing near Frisco, Texas. Neither the flight instructor nor the pilot receiving instruction were injured. The airplane was owned and operated by Ari-Ben Aviator of Addison, Texas. Visual meteorological conditions prevailed and no flight plan was filed for the Title 14 CFR Part 91 instructional flight. The local flight originated from the Addison Airport, Dallas, Texas, at 0835.

According to the flight instructor, the purpose of the training flight was to practice maneuvers and landings to prepare his student for a flight evaluation towards obtaining a commercial pilot certificate. The flight instructor added that after a "normal" pattern to runway 17 at the Frisco Jetport, the instructor stated that after crossing the landing threshold, at an estimated altitude between 50 and 75 feet AGL, his student "decided to close the throttle -which I was not happy with initially- then slightly lowered the nose" to maintain airspeed.

The flight instructor added that at about 15 feet AGL, the pilot receiving instruction "raised the nose to initiate the round out." The flight instructor further stated that the rate of descent was not affected by the increase in pitch, and he and the his student simultaneously reached to apply power.

The airplane landed "particularly hard", bounced and became airborne. The instructor stated that he "knew that the left main gear had been ripped off" and took control of the aircraft. The instructor added that he landed the airplane on its right main landing gear.

In the enclosed NTSB Form 6120.1/2, the flight instructor stated that he felt that a change in the wind direction/speed could have been a contributing factor in the accident. He also noted that the fact that the airport's wind sock was in need of replacement. A fully operational windsock could have provided the pilot a better feel as to the direction and intensity of the surface winds.

The aircraft came to rest with its nose off the edge of the runway in the upright position. Examination of the airplane revealed that the left main and nose landing gear separated from the airframe. Additionally, the left flap assembly was bent, the propeller assembly was damaged, and the outboard portion of the left wing sustained minor damaged.

The recorded winds at the Addison Airport, located 10 nautical miles to the south of the Frisco Jetport, were from 180 degrees at 18 knots. The density altitude, calculated by the NTSB investigator-in-charge, was 2,247 feet.
