 U.S. air-safety regulators are launching a broad review of Southwest Airlines after a string of recent close calls and  other incidents.
 
 The Dallas-based airline has had a number of potential safety incidents in recent months, including flights that  descended to low altitudes too early and a flight that took off from a closed runway.
 
 Southwest acknowledged the Federal Aviation Administration's audit and said it has been working closely with the  agency in reviewing recent episodes. The airline said it had already formed a team of experts and leaders from the  airline, its unions and the FAA to take a close look at its safety system.
 
 "This group is tasked with performing an in-depth, data-driven analysis to identify any opportunities for  improvement. Nothing is more important to Southwest than the safety of our customers and employees," the airline said.
 
 The FAA said it has increased oversight of Southwest to ensure it is complying with federal safety regulations, and  that the timeline of the review will be driven by safety.
 
 Southwest's most recent incident came earlier this month: A July 14 flight descended to as low as 150 feet over  Florida'sTampa Bay -- miles from the runway, according to data from Flightradar24. An air-traffic controller alerted  the pilots and they discontinued their planned approach to Tampa and diverted to Fort Lauderdale.
 
 The FAA has opened investigations into individual instances, but the audit will go further, assessing Southwest's  operations more broadly.
 
 The audit is expected to be completed within three months, according to a government official and a person briefed  on the matter. It is expected to focus on pilot training, various types of approaches for landing, and maintenance  procedures related to opening and removing engine covers and panels, they said.
 
 The review will also delve into the local FAA office that oversees Southwest, the government official said, and as  part of its ramped-up scrutiny, the FAA is expected to assign a safety issue analysis team to examine Southwest's  practices over a longer period.
 
 Southwest's pilots union told members Tuesday that the FAA's Safety Analysis and Promotion Division intends to  perform an in-depth examination of the airline's operations, covering everything from manuals to training and line  operations.
 
 "Expect increased scrutiny on ground events and safety, training on abnormals, turbulence safety, and aircraft  maintenance," the union said in a message to Southwest pilots Tuesday.
 
 United Airlines faced similar federal scrutiny earlier this year after its own operational mishaps. In March, one  of the airline's 25-year-old jets was found to be missing a panel after landing, and another plane lost a wheel during  takeoff in a separate incident that month.
 
 At Southwest, a flight in June took off from a closed runway in Portland, Maine, after pilots overlooked a notice  about the runway's status, according to the National Transportation Safety Board. Another flight that month descended to  a very low altitude several miles away from an airport in Oklahoma City.
 
 In April, a Southwest flight plunged within about 400 feet of the ocean near Hawaii in a mishap while the pilots  attempted to redo a landing in bad weather. Another flight in March veered off course during an attempted landing in  poor conditions and came within 800 feet of the air-traffic control tower at LaGuardia Airport in New York. There have  been two Southwest flights that lost engine covers that were left unlatched.
 
 Southwest's vice president of flight operations, Lee Kinnebrew, in May wrote to employees that the airline was  examining whether there was a disconnect between its procedures, training and performance. He added that the airline was  conducting focus groups in some bases to determine whether there were ways to improve and guard against complacency and  distractions.
 
 "We have more Captains and First Officers in new seats than ever before. We're adapting to an increasingly complex  network with new tools and systems," Kinnebrew wrote.
