A Frontier Airlines Airbus A320-200, registration N227FR performing flight F9-260 from Las Vegas,NV to Tampa,FL (USA) with 166 people on board, was climbing out of Las Vegas' runway 26R after being handed off to departure, when the crew reported cabin crew reported they got some problem with one of their engines (CFM56), flight attendants saying there was some fire. 

Departure responded tower just observed the right hand engine cowl was open. The crew declared emergency and requested to return to Las Vegas. The next departure on runway 26R reported there was some large foreign object debris (FOD) on the runway. The A320 landed safely back on Las Vegas' runway 26L about 15 minutes after departure.

The airline reported the engine cowling came loose and separated from the aircraft. 

Timeline of occurrences and regulatory actions on Airbus A320-family engine fan cowl door loss incidents 

On November 30, 2018, an Airbus A320-214 operated by Frontier Airlines lost the fan cowl doors of engine no.2 upon takeoff from Las Vegas-McCarran International Airport, Nevada, USA. This incident was at least the 45th fan cowl door loss event involving an Airbus A320-family aircraft. 

In July 2015 the U.K. AAIB published an investigation report into a fan cowl door loss accident involving an Airbus A319. Prior to this May 2013 accident , there were a total of 34 previous occurrences of fan cowl door loss on Airbus A320-family aircraft, including 21 events for aircraft fitted with IAE V2500 engines and 13 events for aircraft fitted with CFM-56 engines. Following the A319 accident, three further instances of fan cowl door losses occurred, bringing the total number of occurrences to 38. ASN was able to trace 29 occurrences, of which seven after the publication of the AAIB report, bringing the total to at least 45 occurrences.

A common safety issue among these incidents is the fact that the cowl doors were not closed and latched following maintenance. This was not detected by the engineers, nor by flight crew members during the walk-around check. The design of the fan cowl door latching system, in which the latches are positioned at the bottom of the engine nacelle in close proximity to the ground, increased the probability that unfastened latches would not be seen during the pre-departure inspections.
