Pilot did not follow proceduresIrregularities identified in helicopter crash Several contraventions of aviation regulations were identified as the main cause of the Molteblick helicopter crash in April last year. Several irregularities with regards to aviation procedures were highlighted in the accident report regarding the helicopter crash in the Molteblick area in which the well-known pilot Lambert Roux was killed last year.
These irregularities included that the Roux did not acquire a weather report or file a flight plan, he flew before the Eros airport was officially open, he also flew a different route as suggested by the Air Traffic Controller (ATC) and flew into known instrument meteorological conditions (IMC) conditions without instrument flight rules
(IFR).
The helicopter was also not certified for IFR flight not equipped for these conditions.
The report concluded that the probable cause of the crash was because Roux failed to comply with visual metrological flight conditions and the helicopter crashed in the mountains during flight.
Roux was well-known as a businessman, professional hunter and game expert in Namibia.
He was flying a Namibian privately registered helicopter with registration V5-HFW belonging to Jannie Swart from the Dordabis area on 8 April last year.
The V5-HFW helicopter took off from Eros Airport at 05:50 to a farm in the Dordabis area on a private flight that Roux was hired to fly.
However, when the helicopter did not reach its destination on time the owners of the farm became worried and called the ATC to report it.
According to the report the helicopter R44 took off from Eros Airport in Windhoek for a repositioning flight to a farm near Dordabis in central Namibia.
On-board was Roux who was offloaded at the helicopter earlier that morning by the owner of the helicopter.
The owner then left by road for the farm where a game capturing operation should have taken place near Dordabis.
The flying time for the helicopter to the farm was about 40 minutes. The report found that the fuel on board the helicopter was sufficient and was filled to capacity the previous day.
According to the report no flight plan was filed by the pilot nor was a weather report obtained by Roux for the flight. He did mention the rainy conditions on his first call to the Eros ATC.
Although the airport was still officially closed at the time, ATC responded to the call of Roux out of courtesy and advised him to fly the route to Hosea Kutako International Airport to avoid incoming traffic from the south-east.
According to the report Roux confirmed he would comply and took off while it was still lowlight conditions. He then made a radio call at 05:00 and was given the instruction to make contact with Hosea Kutako International Airport tower to be routed through that airspace and keep clear from descending aircraft inbound the Eros airport.
“Roux however did not comply with this instruction and was already heading towards the mountain range south of Windhoek,” says the report.
According to the report GPS flight data recovered showed that he flew adjacent to the mountain in an easterly direction and then turned abruptly into a southerly direction while commencing to climb.
During the climb the heading changed to a northerly direction and the speed increased to almost the VNE speed (or never exceed speed) in a level flight configuration before the helicopter was pulled into a steep climb again.
The report says that when the speed dropped off to almost hovering, the helicopter turned again abruptly onto a southerly direction picking up speed while descending in a slow left turning manoeuvre reaching the VNE speed again before crashing into the mountain.
The report recommended that pilots must adhere to the regulations laid down in documentation of their licences and that they must refrain from flying outside the scope of their licences. Also Eros airport must ensure non-IFR flights do not depart if the weather demands IFR.
ATC management must also put in measures to ensure operating hours are complied with.
