Beech 23

Full Narrative

On September 10, 2019, about 1220 central daylight time, a Beech A-23, N3555R, was substantially damaged during a forced landing at Northwest Florida Beaches International Airport (ECP) Panama City, Florida. The student pilot/owner and flight instructor were not injured. The airplane was registered to and operated by the student pilot under the provisions of Title 14 Code of Federal Regulations as a part 91 instructional flight. Visual meteorological conditions prevailed, and no flight plan was filed for the flight that departed South Alabama Regional Airport at Bill Benton Field (79J) Andalusia, Alabama about 1130.
The student pilot and his flight instructor had just completed a cross country flight from ECP to 79J, then back to ECP and were conducting airport traffic pattern work, go-arounds and touch and go landings to runway 16. After a normal go-around due to excessive crosswinds, they initiated a no-flap landing for the next attempt. As the student pilot became established on short final, he reported that the approach was normal, but when he attempted to arrest his descent by increasing engine power, the engine did not respond. The student pulled and pushed the throttle several times and the instructor told him to immediately "push it back in to add power." The instructor's first thought was that the throttle cable had broken. After several unsuccessful attempts to regain engine power, the instructor took control of the airplane and attempted a landing, but touched down short of the runway; the airplane bounced hard, struck the approach lights, then settled back onto the runway before rolling to a stop.
According to Federal Aviation Administration (FAA) airmen records, the flight instructor held a commercial pilot certificate with ratings for airplane single engine land, multiengine land, instrument airplane. She also held a flight instructor certificate with ratings for airplane single engine land instrument airplane. She reported 3,150 hours total time and was issued an FAA second-class medical certificate in May 1, 2019.
The student pilot/owner reported 36.1 hours total time with 6.1 hours in the accident airplane make and model and was issued an FAA third-class medical certificate on August 30, 2017.
According to FAA airworthiness and maintenance records, the airplane was issued a standard airworthiness certificate on April 12, 1965. It was a four-place, internally braced low-wing airplane, that was equipped with fixed tricycle landing gear, and a Continental IO-346A, 165-horsepower engine driving a two-blade metal fixed pitch propeller. The airframe and engine had accumulated 3,023 hours total time; the engine accumulated 669 hours total time since overhaul as of the last annual inspection on April 2, 2019. The student pilot purchased the airplane on May 10, 2017.
The weather conditions reported at ECP at 1153 included winds 080° at 7 knots, visibility 10 statute miles, scattered clouds at 4,500 ft, temperature 34° C, dew point 22° C, and an altimeter setting of 30.18 inches of mercury.
Postaccident examination of the airplane revealed that the right wing spar was damaged, and the upper and lower areas on the right wing were buckled. The right gear fairing was buckled, and the left wing was wrinkled where the gear assembly was attached and resulted in damage to the left wing spar. Examination of the airplane's fuel venting system by a mechanic revealed foreign object debris with the consistency of dirt obstructing the right trailing edge fuel vent line. Upon closer examination, it was revealed that the fuel tank vent tube was clogged with mud from an insect, commonly referred to as a "Mud Dauber" wasp.
According to the manufacturer's Airplane Flight Manual (AFM), under Section IV Normal procedures, the preflight inspection includes a specific line item to ensure that the right wing trailing edge, fuel tank vent line, is unobstructed. The flight instructor stated that she did not witness the student pilot conduct the preflight inspection of his airplane.
