By Lucas Liganga The Citizen Chief Reporter Dar es Salaam How safe are Tanzanian skies? This is the inevitable billion-shilling question following the breakdown of the radar at Julius Nyerere International Airport (JNIA) earlier this month.Reliable sources told The Citizen yesterday that the radar, which is used to detect the presence, direction, distance and speed of aircraft, had been out of service since August 3. The radar experienced power supply failure since August 3, rendering it useless. If this situation continues for long, major airlines will stop flying to this airport for safety reasons, one of the sources at JNIA said. Major airlines that fly to and from JNIA include British Airways, Qatar Airways, KLM Royal Dutch Airlines, Swiss International Airlines, Emirates, South African Airways and Ethiopian Airlines. Contacted for comment yesterday, the Tanzania Civil Aviation Authority (TCAA) Director General, Mr Fadhili Manongi, said: We will issue a statement on the matter. I think the ministry (of Transport) will issue a statement today (yesterday). Please be patient. The sources said air traffic controllers at the airport had for the past two weeks been using procedural control, which is a method of providing air traffic control services without the use of radar. They said the method was unpopular with most pilots, who are used to radar and the Global Positioning System (GPS). With radar, an air traffic controller can see all planes flying in our airspace on the screen. Without this facility, air traffic controllers are reduced to relying on guesswork, which is very dangerous, a source said. The sources said a spare part for the radars power supply system could only be supplied by BAE Systems, a British multinational defence, security and aerospace company based in London. The TCAA was alerted about the radars defective power supply in 2010, but no action was taken. Investigations by The Citizen have established that BAE Systems was reluctant to deliver the spare part because the TCAA had not paid for spare parts the British firm delivered for the radar in the past. To make things worse, the sources said JNIA had since 2010 been operating on the single glide path system instead of the required twin system, which makes the landing of planes safer.If this system breaks down completely, JNIA will be just like the airport in Dodoma operation-wise, said one of the sources. Another source said the airport was also running short of flight progress strips used for recording flight information, adding that only two boxes of the strips, which will last up to the end of this month, were supplied from France last month. The sources said TCAA had not paid the supplier of the strips since 2010, adding that 400 strips were being used a day to record flight information. Reached for comment, the Tanzania Government Flight Agency Operations Manager, Captain Kisimbo, quipped: Ask the people who manage the radar. I cant say anything. The Secretary of the Tanzania Air Operators Association (Taoa), Mr Lawrence Paul, expressed his surprise when he spoke to The Citizen by telephone from Mwanza. Im not aware. Im in Mwanza, but Im flying back to Dar es Salaam today (yesterday), he said. The retired traffic controller promised to make a follow-up before issuing a statement today or tomorrow. The Tanzania Airports Authority (TAA) director for JNIA, Mr Moses Malaki, said: This is too sensitive an issue to talk about over the phone. How could one be sure that you are a journalist? Anyone can pretend to be a journalist over the phone. However, Mr Malaki, who said he was in Arusha for a meeting, advised this reporter to get in touch with TCAA officials in Dar es Salaam. Neither TAA Director General Suleiman Said Suleiman nor the Minister for Transport, Dr Harrison Mwakyembe, could not be reached yesterday for comment. |
