The Civil Aviation Authority of the Philippines (CAAP) released a statement saying that the injured passengers, including 3 children, were hurt due to what is commonly referred to as clean air turbulence.
"Clear Air Turbulence is defined as turbulence which is not associated with cloud and therefore cannot be detected visually or by conventional weather radar," CAAP explained.
"It can strike even in the absence of clouds and pilots have no time to warn passengers and crew to get strapped into their seats," it added.
"This is the reason why pilots forewarned passengers to always fasten their seatbelt even the aircraft is on high attitude flight," the statement explained further.
The flight got priority landing and the passengers were immediately treated by the airport medical team when they disembarked in Ninoy Aquino International Airport (NAIA) Terminal 1.
