SUMMARY
The incident was reported to the Air Accident
Investigation Branch by the Kilimanjaro Air Traffic Services shortly after it
occurred. The investigation started immediately.
Whilst descending for
Kilimanjaro International Airport, the flight crew saw an airport (Arusha
airport) and prematurely abandoned the given standard arrival procedure that
would have taken them to the Kilimanjaro runway access. They subsequently landed
at Arusha airport.
The failure of the flight crew to report at given
reporting positions and the failure of the controller to ask for the aircraft
position reports were factors which contributed to the incident.
History
of the Flight
The aircraft was operating Ethiopian Airlines Flight ETH- 815,
a scheduled commercial flight from Addis Ababa to Mombasa via Kilimanjaro
International Airport (KIA). It was carrying 213 passengers and a crew of 10
including two pilots. The fuel load was 18,000 kg which gave an endurance of
0430 hours. The pilot in command testified that he was airborne at 0745 hours
and climbed to a cruising altitude of 36,000 feet. The flight was
uneventful.
Whilst descending to FL 240 the pilot made the first contact
with the Kilimanjaro International Airport. He reported that he had been cleared
by the Dar es Salaam Area Control Centre to descend to FL 240 estimating the
reporting point LOSIN 0937 hours, and touchdown at Kilimanjaro at 0950
hours.
At 0929 hours the pilot was informed by the Kilimanjaro Approach
that runway 09 (the runway with instrument arrival) was not available due to a
disabled aircraft at the approach end. He was advised to use the reciprocal
runway (runway 27) which had 3,300 metres available for the landing. This runway
was not equipped with instrument landing system. The pilot acknowledged the
clearance at 0931hours. He was cleared to FL 120 EVATO 1A arrival, and was
advised to report on breaking visual for runway 27.
At 0943hours the
pilot reported to have airport in sight and advised that he would be joining
left downwind runway 27. The controller instructed Flight ETH-815 to report left
base runway 27. The pilot acknowledged.
At 0945 hours the pilot requested
the position of the disabled Caravan 1. The reply was 300 metres from the
threshold of runway 09 and the available landing distance of 3,300 meters for
runway 27. At 0946 hours the pilot reported left base. He was given the surface
wind 080/02 and cleared to land.
When the controller failed to see to the
aircraft, he tried to raise it on the Kilimanjaro frequency but there was no
reply. It was during the repeated calls that he received a telephone call from
the Arusha tower informing him that ET-AQW had landed at Arusha
airport.
The aircraft made a safe landing on runway 27 of Arusha airport
and stopped within the length of the runway. During an attempted 180 degrees
turn, the nose and main landing gear wheels exited the runway and were stuck in
soft soil. There was no damage to the aircraft. There were also no injuries to
the 223 persons on board.
The aircraft was later towed back to the runway and
made a successful takeoff for Kilimanjaro International airport on 20 December
2013 at 0849 hours. It arrived at Kilimanjaro at 0857 hours with a crew of 5 and
no passengers.
Damage to aircraft
There was no damage to the
aircraft.
The weather
It was a bright, sunny day. The weather does not
appear to be a significant factor in this incident.
Arusha
airport
Arusha airport elevation 4,550 feet has one runway 09/27 which is
1,640 metres long and 30 metres wide. The surface is tarmac (PCN 15) and was in
good condition at the time of the incident. The runway has no turning
pads.
The airport is used by light and medium aircraft. There is one NDB,
AR 391 KHz. Arusha airport is 27 nautical miles (50 km) west of Kilimanjaro
International Airport.
Kilimanjaro International Airport
Kilimanjaro
International Airport, elevation 2,930 feet has one runway 09/27 which is 3,600
metres long and 46 metres wide. The surface is tarmac and was in good condition
at the time of the incident. The navigational aids include one Instrument
Landing System KK frequency 110.9 KHz; One VOR, KV 115.3 MHz; One NDB KB 293 KHz
and two locators, KL 283 KHz; KO 298 KHz. Most of the navigational aids support
instrument approach procedures for runway 09.
The airport has several
standard arrival procedures (STARS) and Flight ETH-815 was cleared for EVATO 1A
arrival into Kilimanjaro.
It was the second time that the pilot in command
was flying to Kilimanjaro. He had previously flown into the airport as an
observer. However, the co-pilot had flown into Kilimanjaro three times before in
the right seat, the last time being September 2013.
Discussion
The
investigations have so far found no technical problems with the aircraft that
could have contributed to this incident. This was corroborated by the company's
Captain who subsequently flew the aircraft out of Arusha.
The pilot
reported nothing unusual during takeoff, climb, cruise and descent. However, the
pilot failed to report at the mandatory reporting point, LOSIN. He was also not
asked by the Kilimanjaro Approach to do so. The only position report he made was
43nm (80 km) from the Kilimanjaro VOR, KV.
During the descent he saw an
airport and prematurely abandoned the given arrival procedure (EVATO 1A) which
would have taken him to position TESOV, and subsequently to the Kilimanjaro
runway axis.
He subsequently joined left downwind for runway 27 Arusha
Airport while believing that he was proceeding to land at Kilimanjaro. His
downwind position report was not challenged by the Kilimanjaro controller, who
should have had him in sight in that position.
