Chris Iwarah, spokesman of the airline, confirmed the incident to reporters.
“The points of contact of the two aircraft were only slightly impacted,” he said.
“But we took the cautious decision to declare them unserviceable to enable a proper investigation of the incident.
“There were no passengers on the two aircraft involved in the incident. We have also revised our flight schedule to cater to our esteemed guests on the 14 sectors the two aircraft were scheduled to service today.
“At the moment, everything is working according to plan and our engineers have already begun repair of the aircraft.”
The Nigerian Civil Aviation authority (NCAA) says it has commenced investigations into the incident, which comes two days after an Aero Contractors plane was engulfed in smoke after 20 minutes of taking off from Port Harcourt International Airport.
The development sparked fear among passengers heading to Lagos.
