G.R. No. L-28692 - Vda. de Abeto vs. Philippine Air Lines, Inc.

The case involves plaintiffs—Comrada Vda. de Abeto, Carmelo Abeto, Cecilia Abeto, Concepcion Abeto, Maria Abeto, Estela Abeto, Perl A. Abeto, Patria Abeto, and Alberto Abeto—being the heirs and administratrix of the late Judge Quirico Abeto.
Defendant-appellant is Philippine Air Lines, Incorporated, a common carrier responsible under its contract of carriage.

On November 23, 1960, at about 5:30 p.m., Judge Quirico Abeto boarded Philippine Air Lines’ flight PI-C133 at Mandurriao Airport in Iloilo City destined for Manila.
His name appeared on the flight’s load manifest as the 18th passenger.
The flight was scheduled for a two-hour trip from Iloilo to Manila; however, the aircraft did not reach Manila, and the next day news emerged that the plane was missing.
After a three-week search, the plane was found to have crashed at Mt. Baco in the Province of Mindoro, with all passengers, including Judge Abeto, killed instantly and their remains scattered.
Personal effects, such as a leather bag bearing the name “Judge Quirico Abeto,” were recovered, corroborating the identity and involvement of the deceased.

Defendant provided records showing that the plane underwent 1,822 pre-flight checks, 364 thorough checks, 957 terminating checks, and 501 after-maintenance checks as part of its quality control measures.
However, evidence presented by the plaintiffs indicated that the defendant failed to perform a necessary pre-flight test to check for possible defects before takeoff.
Testimonies revealed that key safety protocols were breached:

The pilot failed to follow the prescribed route (airway “Amber I”) as mandated by the Civil Aeronautics Administration (CAA).
A student officer, on training, was found at the cockpit with the microphone hanging, suggesting a lapse in proper in-flight supervision.
The pilot did not report his position over or abeam Romblon, a compulsory reporting point required for the flight path.

The death of Judge Abeto, who served as a Technical Assistant in the Office of the President and had previously held significant government positions, resulted in multiple damages claims:

P6,000.00 for wrongful death.
P34,200.00 for the loss of earning capacity based on an estimated remaining life expectancy of 4.75 years at an annual salary of P7,200.00.
P10,000.00 for moral damages due to the emotional and psychological impact on the family.
P1,600.00 for actual damages arising from the loss of personal belongings after deduction of an amount received under a voucher.
P6,000.00 for attorney’s fees and additional sums bringing the total award to P57,800.00.

The familial suffering was further evidenced by the administrative distress experienced by Conrada Vda. de Abeto, who, as administratrix, encountered severe emotional turmoil and physical effects such as sleeplessness and loss of appetite.

Philippine Air Lines contended that the crash was primarily the result of factors beyond its control:

The aircraft was deemed airworthy as substantiated by its certificate from the CAA.
The deviation from the prescribed route was attributed to adverse weather conditions and strong winds, which allegedly forced the plane off course.

The defendant argued that all due diligence, care, and required pre-flight checks were observed, and any deviation constituted a fortuitous event under the provisions of Article 1174 of the New Civil Code.
Consequently, the airline maintained that there was no negligence or malfeasance to warrant the damages awarded.

Expert and eyewitness accounts (including those of Administrative Assistant Ramon A. Pedroza and CAA’s Assistant Director Cesar Mijares) conclusively established that:

The pilot of PI-C133 was off course, failing to follow the designated airway “Amber I” from Iloilo to Manila.
The breach of air traffic rules—by not following the route over Romblon—contributed significantly to the crash.
Such deviations clearly demonstrated a lack of extraordinary diligence as required by law.

Whether Philippine Air Lines, Inc. is liable under its contract of carriage for the death of Judge Quirico Abeto and the consequent damages suffered by his heirs.
Whether the defendant failed to exercise the extraordinary diligence mandated by Articles 1733, 1755, and 1756 of the New Civil Code.
Whether the pilot’s deviation from the established flight route and the failure to adhere to prescribed safety protocols constitute negligence on the part of the carrier.
Whether the evidence overall sufficiently supports the presumption of negligence against the defendant.
Whether the damages awarded by the trial court, including amounts for wrongful death, loss of earning capacity, moral damages, actual damages, attorney’s fees, and costs, are justified in light of the established facts and legal standards.
