2. It is recommended that Exxon Mobil re-design /re-configure the Bonny radio room, so that the radio operator shall have a 360 degree view angle of the airfield.
3. Exxon Mobil should ensure improved meteorological facilities are available at the airstrip to enhance availability of detailed weather forecast and weather observations.
4. Aero Contractors should review its operations and training manual to ensure that task scope for class B, D, etc training is clear and distinctive.
5. Aero Contractors should define and clearly state the role of the training captain and the trainee in an emergency situation.

Three safety recommendations were made in the final report:

1. Aero Contractors should ensure that flight crew comply with company policies on training program.
2. Nigerian Civil Aviation Authority (NCAA) should ensure that operators comply with NCAR 8.5.1.24 as it relates to erasure of flight recorders data after any accident/incident.
3. NCAA should ensure that the owner/operator of Bonny airstrip provides adequate fire coverage and qualified radio personnel.
