What happened
On October 24, 2019, a Zenair CH-2000, registration HI-878, operated by the flight academy Entrenamientos Aeronáuticos Las Américas (ENALAS), was conducting a training flight at Dr. Joaquín Balaguer International Airport (MDJB). During the landing phase, the aircraft experienced a series of successive bounces on the runway. This was caused by an incorrect flare technique during the final approach. The sequence of impacts led to the nose gear making initial contact with the runway, which subsequently caused the aircraft to veer laterally off the paved surface into the adjacent grassy area. There were no injuries to the occupants, and no post-impact fire occurred. The aircraft sustained minor damage to the nose landing gear and the lower fuselage.
The investigation
The CIAA investigation examined the flight operations, the aircraft's maintenance history, and the pilot's training records. Technical analysis confirmed that the aircraft's weight and balance were within manufacturer limits, with an estimated takeoff weight of 596.6 kg, well below the maximum takeoff weight of 703 kg. The investigation also reviewed the pilot's qualifications and the academy's training oversight. Maintenance records for the engine, propeller, and 100/50-hour inspections were reviewed and found to be in order. Meteorological conditions at the time of the event were noted as favorable for flight operations.
Findings
- The primary cause of the incident was the incorrect application of the flare technique during the landing phase.
- The aircraft experienced a series of bounces on the runway due to the improper flare.
- The nose gear made contact with the runway, leading to a lateral excursion into the grass.
- The aircraft was operating within its certified weight and balance limits.
- The aircraft's maintenance status was compliant with regulatory requirements.
