Helicopter Crash Pilot Was Fit and Held Valid License

The Long Lellang helicopter crash investigation involves a preliminary aviation safety inquiry conducted by the Air Accident Investigation Bureau (Biro Siasatan Kemalangan Udara, or BSKU) under the Ministry of Transport Malaysia. The investigation focuses on a Eurocopter Deutschland GmbH MBB-Bo105 S helicopter (registration 9M-LLF) operated by Malaysian aviation firm Rotorwing (Malaysia) Sdn Bhd, which crashed near the Long Lellang STOLport in interior Sarawak on 8 September. The probe addresses regulatory compliance, operational safety, and airworthiness standards to inform Malaysian civil aviation regulators, rural air service operators, and the public regarding flight operations in remote Borneo corridors.

Key Facts

Was the Pilot Medically Fit and Duly Licenced for the Flight?

Captain Zainol Afiq Bee Sham was fully licenced and medically certified to operate the aircraft during the flight. According to BSKU, he held a valid Commercial Pilot Licence for helicopters with a Bo-105 type rating valid until 31 January 2027, alongside an unexpired medical certificate issued on 26 January following an official examination.

The bureau confirmed the 30-year-old aviator possessed appropriate statutory clearances under prevailing Malaysian civil aviation regulations. His flight records documented 1,825.5 total flying hours, comprising 915 hours and 50 minutes on the Bo-105 helicopter type, 81 hours and 48 minutes flown across the preceding 90 days, and a mandatory rest period of 22 hours prior to the mission.

"Zainol memiliki Lesen Juruterbang Komersial (helikopter) yang sah, dengan kelayakan mengendalikan pesawat jenis Bo-105 dan lesen itu sah sehingga 31 Januari 2027. Beliau turut menjalani pemeriksaan perubatan pada 26 Januari tahun ini, dengan sijil perubatan sah sehingga 31 Januari 2027. Juruterbang berkenaan memiliki lesen, kelayakan dan kelulusan sewajarnya untuk melaksanakan penerbangan mengikut peraturan berkuat kuasa. Selain itu, beliau mempunyai sijil perubatan sah dan berada dalam keadaan sihat dari segi perubatan untuk menjalankan penerbangan."

Biro Siasatan Kemalangan Udara (BSKU) Preliminary Report

Official findings confirm Captain Zainol Afiq Bee Sham held a valid Commercial Pilot Licence and medical clearance through 31 January 2027 with 1,825.5 total flight hours.

Was the MBB-Bo105 S Helicopter Certified Airworthy Prior to the Incident?

The MBB-Bo105 S helicopter was certified airworthy and legally registered at the time of the incident. BSKU verified that the aircraft, manufactured in 1991 by Eurocopter Deutschland GmbH and registered as 9M-LLF under Rotorwing (Malaysia) Sdn Bhd, held an unexpired Certificate of Registration and a valid Certificate of Airworthiness.

Documentation examined by investigators showed the aircraft's Certificate of Registration remained valid until 28 July 2029, while its Certificate of Airworthiness was active until 4 August 2027. Routine operational records indicated that the twin-engine light helicopter was mechanically fit for service, with all communication frequencies operating nominally throughout the scheduled multi-leg sector from Miri to rural Sarawak airstrips.

The Eurocopter MBB-Bo105 S registered as 9M-LLF held an active Certificate of Airworthiness valid until 4 August 2027 and was confirmed airworthy before departure.

What Weather Conditions Were Recorded Around Long Lellang STOLport?

Weather conditions around Long Lellang STOLport were assessed as generally favourable with visibility exceeding 10 kilometres. The Malaysian Meteorological Department (MetMalaysia) confirmed that no thunderstorm or rain activity occurred within a 20-nautical-mile radius of the airstrip between 8:00 am and 3:00 pm, prior to moderate cloud convection emerging around 4:00 pm.

Official aviation weather logs indicated that surface wind observations were active for the airfield, with no wind shear advisories or airport warnings in effect during the flight window. Furthermore, no Significant Meteorological Information (SIGMET) or Airmen's Meteorological Information (AIRMET) advisories were active within 20 nautical miles, and the pilot transmitted no emergency distress calls before the crash.

MetMalaysia radar and satellite data recorded clear visibility exceeding 10 kilometres with zero thunderstorm activity within 20 nautical miles of Long Lellang STOLport until 3:00 pm.

What Was the Flight Path Recorded by the Spider Track Tracking System?

The flight followed a multi-stop itinerary across Sarawak from Miri to Ba'Lai, Selungo, and Long Lellang before contact ceased. Spider Track tracking logs revealed the helicopter initiated engine start at 10:15 am, departed Miri at 10:24 am, and landed at Ba'Lai at 11:39 am, where the engine was shut down.

Operations resumed at 1:36 pm toward Selungo, touching down at 2:02 pm for refuelling prior to the final leg. The pilot restarted engines at 3:17 pm bound for Long Lellang STOLport, with the final transmission captured at 3:27 pm at a location approximately 3 nautical miles from the destination runway.

Spider Track operational data placed the helicopter's final recorded position at 3:27 pm approximately three nautical miles from Long Lellang STOLport.

Who Is This For in Malaysia?

Aviation safety analyses of remote operations directly serve Sarawakian rural transport authorities, flying doctor services (Perkhidmatan Doktor Udara), and commercial rotorcraft charters. These organisations navigate microclimates, tropical convective cloud activity, and mountainous terrain where short take-off and landing ports (STOLports) represent vital community lifelines.

Operating light utility helicopters across the interior of Borneo requires compliance with civil aviation oversight, strict refuelling stop management, and satellite flight tracking systems like Spider Track to maintain accountability across isolated air routes lacking full terrestrial radar coverage.

Common Questions

Was Captain Zainol cleared medically to fly the helicopter?

Yes. The Air Accident Investigation Bureau confirmed Captain Zainol Afiq Bee Sham was medically fit, having undergone a medical examination on 26 January, with his official medical certificate and Commercial Pilot Licence remaining valid until 31 January 2027.

Were adverse weather warnings active at Long Lellang STOLport during the crash?

No adverse weather warnings were active. MetMalaysia recorded visibility exceeding 10 kilometres with no thunderstorm activity within 20 nautical miles between 8:00 am and 3:00 pm, and no wind shear alerts, SIGMET, or AIRMET notices were in effect.

When and where was the helicopter's final tracking signal recorded?

The final signal was recorded at 3:27 pm via the aircraft's Spider Track tracking system on 8 September. The data placed the MBB-Bo105 S helicopter approximately 3 nautical miles away from its intended destination at Long Lellang STOLport.
