Investigation Summary
The flight was operating as a substitute for a cancelled Turkish Airlines service, carrying 74 passengers and 7 crew members. The explosion occurred while the aircraft was still climbing, which likely saved the airframe from a catastrophic structural failure that might have occurred at a higher cruising altitude with greater pressure differentials. Immediately following the blast, the pilots alerted Mogadishu tower to report a pressurization problem, though they did not initially declare an emergency. Investigation by Somali authorities, supported by the FBI, revealed that the explosive device was a laptop bomb containing TNT. CCTV footage from Mogadishu airport showed two men, identified as airport employees, handing the laptop to the suspect, Abdullahi Abdisalam Borleh, before he boarded. Borleh had reportedly entered the aircraft in a wheelchair to bypass standard security screening before moving to a regular seat. The captain, Vladimir Vodopivec, later criticized the airport's security as 'zero,' noting that 20 to 30 people would come to the tarmac without badges or yellow vests, making it impossible to know who was authorized to be there.
Final Conclusions
The Somali Air Accident Investigation Authority and military courts concluded the event was a planned suicide bombing. In May 2016, a Somali military court sentenced ten individuals for their roles in the attack, including the two airport workers who provided the laptop. The investigation confirmed that the bomb was intended to destroy the aircraft and kill all on board, but the 20-minute departure delay and the resulting lower altitude at the time of detonation prevented a total hull loss.

Captain
64-year-old Serbian pilot Vladimir Vodopivec.
Systems & Failure Modes
Fuselage Structure
The aircraft skin behind the R2 door suffered a large breach due to the localized high-pressure wave of the explosion.
Cabin Pressurization
The explosion caused an immediate loss of cabin pressure, though the effect was mitigated by the aircraft's relatively low altitude at the time.
Interesting Facts
- 01The aircraft was a 19-year-old Airbus A321-111 owned by Hermes Airlines and operated by Daallo Airlines under a lease.
- 02The aircraft featured a 220-seat economy-only configuration.
- 03The bomb was concealed inside a laptop computer and contained traces of TNT.
- 04The intended target was a Turkish Airlines flight, but passengers were transferred to Daallo after the Turkish flight was cancelled due to weather.
- 05Three passengers on board sustained injuries in addition to the one fatality.
- 06The aircraft was written off due to substantial structural damage to the fuselage.
- 07The suspect was a 55-year-old male who had reportedly obtained a Turkish visa under questionable circumstances.
Safety Actions & Advisories
Airport Security Overhaul
Following the incident and the captain's reports of 'zero security,' Somali authorities implemented stricter badge and vest requirements for tarmac personnel at Mogadishu.
Screening Procedures
Enhanced screening for electronic devices, specifically laptops, was introduced at Aden Adde International Airport to detect concealed explosives.

Turkish Airlines Target Dispute
Reference ↗While Al-Shabaab claimed they targeted Turkish Airlines due to Turkey's NATO membership, investigators examined whether the bomb was specifically timed for the Daallo flight or if the transfer of passengers forced a change in the terrorists' plans.
