2017-03-07 Westjet Airlines Boeing 737-800 too low near Sint Maarten
The 737 flew very low above the sea on final approach to Sint Maarten Island until a go-around was initiated. The flight made a safe landing 45 min later.
Westjet Flight WS 2652 from Toronto was on approach to Princess Juliana Airport, Sint Maarten, Neth. Antilles. The 737 was following a VOR DME approach (without altitude guidance by the autopilot) to runway 09. About 2 miles out, the aircraft descended below the proper approach profile.
It was about 0,7 NM out over Maho Beach Bay when the flight came extremely low over the water until the pilots initiated a go-around from an estimated altitude of about 25-30 meters.
The aircraft climbed out to 3,800 ft and entered a holding west of the airfield. About 45 min later the pilots made a safe landing on their 2nd attempt.
At the time local weather consisted of overcast skies associated with gusty winds above 20 knots, rain and the visibility was reduced to about 2,000 meters.
The airline denied in a press statement the following day, there was no deviation from the normal approach path, saying: “According to the information I have been given there was nothing unusual about the first approach.”
According to credible eyewitness accounts, the 737 flew substantially lower than any other of the arriving aircraft. Passenger footage from a right-hand window seat confirmed the aircraft descending close to the ocean without a sign of any turbulence. Precipitation increased before a female passenger exclaimed: „Oh my god, we are so low.“ Seconds later the go-around was initiated. (see video below)
That same female passenger continued to report that it took about 10 minutes before the cockpit made any announcement. When they did so, they apologized for being silent saying they’ve been just too busy to address to the passengers. They justified the go-around by allegedly saying it was due to adverse weather conditions and poor visibility and that they will wait for the weather to pass. The pilots concluded they would be able to land soon.
The Canadian Transportation Safety Board has launched an investigation. [TSB-Investigation Website].
Westjet statement excerpt about flight 2652:
„..In this case, our crew experienced rapidly changing weather conditions and as a result descended below the normal glide path on the approach to the landing. The crew recognized the situation, and the regularly trained and desired outcome was obtained – a safe missed approach to a safe landing…“ Read the full press statement
Canadian investigation authority TSB changed the incident classification from „non-reportable“ to „reportable“.
On 2018-06-04 Canadian Transportation Safety Board (TSB) released the final investigation report. Available HERE.
„At 1534:12, when the aircraft was 40 feet above the water and 0.3 nm from the runway threshold, the crew initiated a go-around. The lowest altitude recorded by the EGPWS during the descent had been 39 feet AGL.“
