Event Description
During an approach to land, the flight crew received an engine fire warning. The crew executed engine fire emergency procedures and completed a single-engine landing. After landing, smoke was reported coming from the #2 engine. The captain ordered an evacuation of the airplane.
Evacuation and Slide Deployment
When exit door 1R was opened, its slide deployed automatically. However, the slides for exit doors 1L and 2R did not automatically inflate; both were inflated manually. Another flight attendant could not rotate the door handle on exit door 2L. With assistance from a passenger, the door was opened, at which point the escape slide inflated into the airplane, blocking both aft exits.
Passenger Injury
A passenger exited through the 1L door and fractured her ankle. According to one of the flight attendants, the passenger did not jump out of the exit as directed, but instead sat down and slid out.
Investigation
Investigation revealed that the operator had received approval for an alternate means of compliance for AD 85-25-04. This airworthiness directive addresses escape slide modifications, testing, and inspections for certain Boeing 737 models (737-100, 200, and 300).
