What happened
On November 30, 2017, a Piper 28-235, registration HK1573G, departed from Guaymaral Aerodrome (SKGY) for a scheduled flight training mission. The flight, conducted by an aviation school, was intended to cover the instrument training phase within the SKE25 training zone.
During the flight, the aircraft experienced a significant technical issue. The instructor pilot requested priority landing at Guaymaral and notified Air Traffic Control (ATC) that firefighting assistance was required. As the aircraft attempted to return, it suffered a loss of altitude and airspeed. Near the Zipaquirá VOR, the instructor decided to divert to the Las Acacias emergency landing strip (SKAI) in Nemocón.
While approaching the emergency strip, the aircraft entered Instrument Meteorological Conditions (IMC) due to heavy low-level fog. The aircraft subsequently struck a tree and crashed, resulting in the fatalities of both the instructor and the student pilot.
