Finnish aviation news site lentoposti.fi has posted a news item on a near stalling incident at Kittilä (EFKT), in Northern Finland:
Suomen onnettomuustutkijat avustamaan norjalaisia Kittilässä tapahtuneen vaaratilanteen tutkinnassa | lentoposti.fi
Short summary in English:
The B737 registration LN-BYM (NAX5630) was flying the ILS 34 approach to Kittilä (EFKT), in Northern Finland, when at 3250 ft on the glideslope with autopilot engaged and flaps partially extended the aircraft started a sudden climb with full thrust, at the same time letting the airspeed decrease near stalling speed. The aircraft climbed 1500 ft during the incident before the pilots regained control.
The next approach was successful and no technical faults have been found so far in the aircraft.
Norway's Accident Investigation board (SHT) is investigating this incident together with it's Finnish counterpart, NTSB and Boeing. SHT has the FDR and some aircraft parts in its possession.
Some facts which may be irrelevant in this case: EFKT34 ILS G/S is 3.4 degrees steep, with typically tailwind conditions (no precision approach to 16 available), 2.5 km runway and often slippery runway conditions. Depending on time and day the airport may be manned either with an ATCO (TWR) or an AFIS person.
Any ideas from B737 pilots?
