Unaware of what the cause might have been they decided to make a pitstop in Nagpur, India, to refuel the plane before completing their flight. However, just as they were beginning to prepare for landing they realized what was wrong — their landing gear was never retracted.
"When preparing to land, they decided to lower the landing gear," a source told the Times. "At this point they realized that the wheels had been out all the while from Kolkata."
Ideally, pilots retract the plane’s wheels after takeoff. Considering the weight put on the flying bird, forgetting to do so resulted in the increased fuel consumption.
While the plane did make a safe landing in Nagpur, the pilots, who were flying with nearly 100 passengers, were put on leave.
"After take off, both the women pilots forgot to retract the landing gear. As a result, the brand new Airbus A-320 continued to ascend at a very low climb rate," the Times’ source explained. "The plane finally gave up climbing after reaching an altitude of 24,000 feet as the extended landing gear meant very heavy drag."
"It then levelled out and flew at 230 knots for the next 1.5 hours."
As Air India looks into the matter, it’s safe to say these pilots won’t ever forget to check off the status of the landing gear when and if they’re ever given back their wings.
