Dar es Salaam. Precision Air has grounded one of its ATR- 72 aircraft after it was hit by a flock of birds before landing at the Mwanza Airport on Sunday.
Lake areas such as Mwanza and plain game areas in other parts of the country are considered hazardous for air safety due to birds that often fly at high altitude.
On Sunday December 9, the birds hit Precision Air’s flight PW 722, which was flying from Nairobi via Kilimanjaro to Mwanza and caused some damages.
Nonetheless, the plane managed to land safely without any casualties. It had four crew members and 68 passengers on board, the airline has confirmed to The Citizen.
Bird strikes are a significant threat to flight safety, and have caused a number of accidents with human casualties. Majority of bird strikes are known to cause little damage to the aircraft. However, the collision is usually fatal to the bird(s) involved.
Eliminate birds at landing sites
Precision Air’s chief executive officer Sauda Rajab told The Citizen during an interview that the birds were a great risk to air safety at airports where cases of bird strikes are notorious.
“The birds not only pose a risk to passengers and the crew, but also cause a great loss. They can damage the engines. It means now that our engineers have to work on this aircraft before it can start flying again,’’ said Ms Rajab. “Imagine when the engine is damaged and we have to pay up to two million dollars to replace it,’’ she explained further.
She suggested that strong mechanisms should be put in place to deal with the birds. “Our pilots are well-trained to deal with such situations but I think long-term solutions have to be found at Mwanza Airport. Such cases have also been reported with other airlines,’’ she said.
“I know that at Kilimanjaro International Airport, research has been done and this led to some interventions. I do believe the same can be done for Mwanza Airport where cases of bird strikes have also been reported quite often,’’ he noted.
Later yesterday a statement from Precision Air said: “…a team of engineers is assessing the extent of damage to the aircraft and to determine the necessary course of action.”
“Being short of one aircraft for our commitment, adjustments had to be made to our flights from which some passengers may be inconvenienced in the short term,’’ the statement added.
Airports authority speaks out
The Tanzania Airports Authority (TAA) director general Richard Mayongela said he had assigned a team to look into the matter to find ways of addressing the cases of bird strike at Mwanza Airport.
“There are committees involving the youth, who have always been controlling the birds…in the latest case, I think they were not on the ground to intervene,’’ said Mr Mayongela when The Citizen sought to know what measures had been taken so far.
“As we are speaking now, I have assigned a team of people to intervene, but [as the government] we will go further into finding long-term measures, including learning from countries facing a similar problem. We also want to start employing technology,’’ he said.
Known concentration areas for the birds have also been noted in West Kilimanjaro, Dodoma and Singida. Experts say the birds could constitute a great hazard after good rains when breeding takes place.
The International Civil Aviation Organisation (ICAO) reported 65,139 bird strikes for 2011–14, and the Federal Aviation Authority counted 177,269 wildlife strike reports on civil aircraft between 1990 and 2015, growing 38 per cent in seven years from 2009 to 2015. Birds accounted for 97 per cent.
