In a ruling that clarifies the responsibilities of pilots and air traffic controllers, the Supreme Court held that the primary responsibility for avoiding collisions rests with the pilots in command of aircraft. This decision underscores the importance of adhering to air traffic rules and exercising due diligence, even when clearances are given by air traffic control. The case highlights that pilots cannot blindly rely on clearances but must maintain vigilance to ensure the safety of their aircraft and passengers, thereby establishing a precedent for liability in aviation accidents.
Cleared for Takeoff or Cleared for Disaster? Deciphering Negligence in a Runway Collision
This case stems from a collision that occurred on April 2, 1996, at Manila International Airport (now Ninoy Aquino International Airport) between a Philippine Airways Corporation (PAC) Twin Otter aircraft and a Philippine Airlines (PAL) Boeing 737. The PAC aircraft, after disembarking passengers, was taxiing to its hangar, while the PAL aircraft was preparing for takeoff. As the Twin Otter crossed runway 13, it collided with the Boeing 737, resulting in significant damage to both aircraft and injuries to the pilots. The ensuing legal battle sought to determine who was at fault, focusing on the actions of the pilots and the air traffic controllers from the Air Transportation Office (ATO).
The central issue revolved around determining which party’s negligence was the proximate cause of the collision. The Regional Trial Court initially ruled that the negligence of the ATO traffic controllers, along with the PAL pilots, were jointly and severally liable. The Court of Appeals affirmed this decision but later modified it to absolve one of the air traffic controllers. The Supreme Court, however, reversed the appellate court’s decision, placing the primary blame on the pilots of the PAC Twin Otter.
The Supreme Court anchored its decision on the **Rules of the Air**, which explicitly state that an aircraft taxiing on the maneuvering area of an aerodrome must give way to aircraft taking off or about to take off. In this context, the PAL Boeing 737 had the right of way, as it was in the process of taking off. The Court emphasized that the PAC pilots were grossly negligent in disregarding this rule. Gross negligence is defined as:
“one that is characterized by the want of even slight care, acting or omitting to act in a situation where there is a duty to act, not inadvertently but willfully and intentionally with a conscious indifference to consequences insofar as other persons may be affected.”
The Court found it implausible that the PAC pilots did not see the Boeing 737, which was only 200 meters away with all its lights on. This led to the conclusion that the PAC pilots did not properly check for oncoming aircraft before crossing the active runway. Moreover, the PAC pilots had prematurely requested clearance to cross the runway while still 350 meters away. The ATO noted that they should have made a full stop at the holding point to request an updated clearance right before crossing, which would have allowed the ATO to assess the presence of any aircraft taking off. This failure to adhere to proper procedure was deemed a significant factor contributing to the accident.
The Rules of Air Control also place significant responsibility on the **pilot-in-command**. According to the Rules of Air Control:
“The pilot-in-command of an aircraft shall, whether manipulating the controls or not, be responsible for the operation of the aircraft in accordance with the rules of the air, except that he may depart from these rules in circumstances that render such departure absolutely necessary in the interest of safety.”
Furthermore, the pilot-in-command has the final say regarding the aircraft’s disposition and can request amended clearances if necessary. Clearances from air traffic control are meant to expedite and separate aircraft but do not authorize violations of safety regulations. The court highlighted the importance of pilots exercising their own judgment and not blindly following clearances that may compromise safety. The clearance to cross runway 13, given prematurely, was not an absolute license for the PAC pilots to recklessly maneuver across an active runway.
In contrast, the air traffic controller was found to have properly issued the takeoff clearance to the Boeing 737. The court noted that there was no evidence of irregularity in this clearance. While the ATO traffic controllers may have been contributorily negligent in granting the premature request from the PAC pilots, this did not absolve the PAC pilots of their primary responsibility to comply with the Rules of the Air.
The Supreme Court underscored that the air traffic controller’s clearance does not relieve a pilot of their responsibilities. The Rules of Air Control explicitly state that:
“Clearances issued by controllers relate to traffic and aerodrome conditions only and do not relieve a pilot of any responsibility whatsoever in connection with a possible violation of applicable rules and regulations.”
The court referenced Santos v. BLTB, applying the principle that a motorist proceeding correctly on their side of the highway can generally assume that an approaching motorist on the wrong side will return to their proper lane. Similarly, the PAL pilots could reasonably assume that the taxiing aircraft would respect their right of way and not cross the active runway during their takeoff roll.
Ultimately, the Supreme Court concluded that the **proximate cause** of the collision was the gross negligence of the PAC pilots. Proximate cause is defined as:
“that cause, which, in natural and continuous sequence, unbroken by any efficient intervening cause, produces the injury, and without which the result would not have occurred.”
Because the PAC pilots disregarded the PAL aircraft’s right of way and failed to request an updated clearance before crossing the active runway, they were held liable for the collision. Under Article 2179 of the Civil Code, a plaintiff whose negligence is the immediate and proximate cause of their injury cannot recover damages. Therefore, the PAC pilots were not entitled to damages.
The Court upheld PAL’s counterclaim for actual or compensatory damages amounting to US$548,819.93, representing lease charges incurred while the Boeing 737 was out of service. The GSIS, as the insurer of the Boeing 737, was subrogated to PAL’s rights to claim damages and was entitled to reimbursement of US$2,775,366.84, the amount paid for the repair of the aircraft. Casiño and Isaac, the pilots of the PAL aircraft, were awarded moral damages, exemplary damages, and attorney’s fees due to the gross negligence of the PAC pilots.
