The opinion of the court was delivered by: DAVIS
This action was commenced by the plaintiff against the several defendants jointly for damages resulting from a midair collision between two private airplanes attempting to land at the North Philadelphia Airport. Robert T. Wilson and Richard C. Hochrein were the pilots of the private planes and the airport tower was under the jurisdiction of the Federal Aviation Agency, manned by air traffic controllers in the employ of the Government. Shortly before trial, plaintiff executed a joint tortfeasor release with the defendants, Robert T. Wilson and the Civil Air Patrol. The trial proceeded non-jury against the United States as provided in the Federal Tort Claims Act, 28 U.S.C. § 1346(b), 2402. This opinion, therefore, will deal only with the claim of negligence alleged against the United States.
The decedent, Richard C. Hochrein, was alone in his Cessna 140 Aircraft flying on September 30, 1959 from the Blairstown, New Jersey Airport to the North Philadelphia Airport. At 2:15 P.M., EST., Hochrein radioed the North Philadelphia Tower and was instructed by the tower, through Frank W. Toon, Jr. the air traffic controller in charge, to enter the traffic pattern for runway 15 on the downwind leg. Upon entering the pattern Hochrein again radioed the tower and after Toon had sighted Hochrein in the pattern, Toon acknowledged his transmission and cleared him to land on runway 15.
Almost immediately thereafter, Toon sighted a non-radio equipped Aeronca aircraft flying the same pattern as the Cessna, but behind, above and outside the Cessna, on the downwind leg. This plane was piloted by defendant Wilson and had been making practice 'touch and go' landings on runway 15 shortly before the sighting by Toon mentioned above. The Aeronca was based at the North Philadelphia Airport, known to Toon, and visually identified by Toon and the other traffic controller on watch in the tower, Raymond Kevles.
Toon used the portable light gun to signal the Aeronca to exercise caution. The light gun is used to control non-radio equipped aircraft in visual flight rule conditions which existed at all times pertinent to this action.
This light signal was not acknowledged by the Aeronca.
However, the Cessna was in clear sight and should have been seen by Wilson in the Aeronca. The signal given the Aeronca by Toon on the downwind leg was a sufficient precaution for the situation as it then existed.
As the planes turned onto the base leg, first the Cessna then the Aeronca, Toon again signalled Wilson in the Aeronca to exercise caution due to his traffic, i.e. the Cessna ahead of him. At this point in the pattern, this signal given by Toon was sufficient to discharge his duty to supervise and control the traffic within the area of his jurisdiction in light of the weather conditions and visual flight rule then in effect. But Wilson in the Aeronca again failed to acknowledge Toon's signal. To this point, Toon was justified in presuming that Wilson could see, and was aware of, the traffic ahead of him. The Cessna was in clear sight and it is a pilot's duty to keep watch and avoid other aircraft.
But it is also a pilot's duty while in a control zone to be attentive to signals emanating from the control tower. After Wilson in the Aeronca failed to acknowledge his first two signals, Toon should have been aware of the possibility that Wilson not only did not see the light signals, but did not see the Cessna as well. Though this would mean that Wilson violated several air regulations and was negligent, this conduct up to this point was a clear warning that Wilson might continue in his lack of due care.
A person can not be held liable for another's negligence, but the second party's negligence can arise from a duty imposed as a result of the original negligence. If Wilson was negligent, and we consider he was, the question of the defendant United States' liability rests on whether or not Toon had a duty to take some action to warn Hochrein in the Cessna of the Aeronca's presence.
An air traffic controller's duty to aircraft in his control zone is contained in the Air Traffic Control Rules (14 C.F.R. 617) and the ANC Manual.
These rules and regulations have the force and effect of law.
The regulations outline Toon's duty as air traffic controller and in effect require a controller to aid and assist the pilots of aircraft within the control zone. This assistance takes a variety of forms including the issuing of clearances and disseminating information regarding traffic in the pattern and control area.
We agree that the main responsibility for the safe conduct of an aircraft in the control zone under visual flight rule conditions rests with the pilot of each aircraft. We also agree that the controller may be analogized to a traffic officer at an intersection. In this factual situation as it developed, pilot Hochrein was responsible for the safety of his aircraft and, after receiving his clearance to land,
remained primarily responsible for the movement of his aircraft. Decedent Hochrein was required to follow his clearance, not blindly, but correlative with his duty to exercise care for his own safety from everything of which he was aware. There is nothing in the record which would indicate to this Court, and we so find, that Hochrein was aware of the Aeronca in the pattern for runway 15 nor that he should have been aware of the Aeronca's presence. If a traffic officer signals a car to proceed through an intersection knowing that the driver can not see an approaching vehicle, which the officer knows has just passed through two other signals to stop, would it not be incumbent upon the officer to at least warn the driver of the other's presence? We think it should.
Controller Toon failed in his obligation to pass on information which may be necessary for a pilot to discharge his responsibility for his own safety. When Wilson failed to acknowledge Toon's cautionary signals, a duty
arose to at least inform Hochrein of the Aeronca's presence so that Hochrein would be aware of a possible danger to his landing and take it into consideration in following the 'mandatory'
clearance or deciding that an emergency exists and thereby forego landing. Toon was negligent in this respect and this negligence was a cause of the ensuing collision and death of pilot Hochrein.
We turn now to the issue of damages. This action was brought under the Pennsylvania Wrongful Death Act, 12 P.S. §§ 1601-1604, and the Survival Act, 20 P.S. §§ 320.601, for loss accruing to Hochrein's family as a result of his ...
