PAL's Aircraft Are Rigorously Maintained While In Storage

Philippine Airlines (PAL) had temporarily suspended regular passenger flights due to government-imposed travel restrictions in order to stop the spread of the Coronavirus. As such, they had to put their aircraft into storage while awaiting to be used once the crisis 'dies' down.
However, storing an aircraft is not only about parking it, dusting it off, and covering its engines. The process of actually storing an aircraft is very tedious as all have to be kept in complete flying condition everyday and at anytime they might be needed like special flights.

In a report from Bloomberg, it said that aircraft can’t simply be dusted back into action. They need plenty of work and attention while in storage, from maintenance of hydraulics and flight-control systems to protection against insects and wildlife — nesting birds can be a problem. Then there’s humidity, which can corrode parts and damage interiors. Even when parked on runways, planes are often loaded with fuel to keep them from rocking in the wind and to ensure tanks stay lubricated.

PAL technicians ensure that all airplanes are in airworthy condition, ready to be used anytime. Everything are checked. Hydraulics, sensors, tires, small particles on the engines, flaps, rudder, avionics, all are basically monitored and checked by PAL technicians. Nothing is left unchecked. Scheduled rigorous maintenance are always performed on these airplanes, ensuring their safety once they are "called" from storage.

On the ground, these jets are pampered. Engines are covered, sensors are also protected, and sun shades are placed on the cockpit windscreen.

PAL still uses some of these aircraft for special repatriation and cargo flights but they fly to great distances like to North America and London.

These daily checks, maintenance, and repair of certain components if needed happen daily as though they are currently flying. This is why storing an aircraft if also very expensive. Maintaining them in complete airworthy condition is costly to the airline.

However despite the costs incurred, it is assured that once air services return, these airplanes are ready to fly passengers and cargo safely.
