Airport Construction Hazards
Construction activities at an airport are sure to complicate normal procedures. To maintain safe operations, local controllers must sustain an unusually high degree of vigilance, particularly when dealing with construction equipment in their midst. Some controller reports explain: landings: one pilot damaged a flap and the fuel tank on a barricade across the runway. Another crew apparently was on “mental autopilot” during takeoff, and forgot that the airport construction had caused a change in their usual departure routine.
s ATC currently operates a portable tower due to
obstructed views of runways 1/19 caused by the construction. A construction crane was recently erected in front of the portable tower, again causing obstructed views of runways 1/19 and also 14/32. Of primary concern, the view of the intersection of these runways is obstructed. This has caused numerous “close calls,” because controllers in this portable tower cannot see aircraft in or near this intersection. Construction-related vehicle traffic in aircraft movement areas can also be a major cause of workload, as another controller reports:
s The published procedure is quite clear: “…turn to a 205°
heading within 1 DME of the airport.” We blew it and were flying runway heading when Tower had to remind us to make the turn. The reason we failed to execute the maneuver properly was due to the use of runway 25 when we normally operate from runway 21, which was closed for construction. The departure from runway 21 is basically runway heading, and that is what we had in our minds. Rather than having an unusual operation trigger extra study, we pressed on and blew the turn. Another lesson: take more care when operations are different than normal. Our reporter’s advice applies to everyone operating near an airport construction area—flight crews, controllers, ground crews, and construction crews.
s Air carrier X was cleared for takeoff. I observed a van,
used to shuttle tower personnel in and out, cross the holdshort line at taxiway A. I instructed X to abort his takeoff. Due to the amount of construction, we are forced to [get vehicles across] active runways hundreds of times daily. Another problem that surfaces near airport work areas is the temporary signs directing pilots to alternate taxi routes.
Spring Sprucing Tip
Spring is the time of year when airplane owners think of getting that aircraft spruced up after a long, cold winter in the hangar or out on the ramp. But let the “sprucer” beware:
s Due to extensive construction on the airport, some signs
and markings are non-standard. A corporate aircraft passed his turn and crossed the departure end of runway 28. Air carrier Y was not rolling, but had been cleared to do so. I cancelled Y’s clearance just prior to its beginning its departure roll.
s On final, I attempted to put down the landing gear.
The gear appeared to operate normally, but the right main gear light was not illuminated. However, all other indicators that the gear was locked down were functioning normally. I recycled the gear, and also tested the gear-locked horns for proper operation. I advised the Tower of the situation, executed a fly-by, and was advised the gear was down. I made the approach again and set the aircraft down when the right main gear collapsed. Minor damage resulted. When the mechanics lifted the aircraft, the gear came right down, but the downlock hook didn’t function properly. I had just picked up the aircraft from the paint shop, where they apparently got too much overspray on the gear, resulting in the hook binding. The reporter suggested that the paint shop be requested to jack up the aircraft and exercise the landing gear several times before releasing the aircraft to the owner.
On Your Mark… Stop!
Pilots also report problems with airport construction area signage and surface markings. Temporary or paintedover markings may be difficult to see, particularly at night or in wet weather. Or, as in the next report, extraneous objects may be mistaken for markings.
s Captain landed 300 feet short of displaced threshold.
ATIS out and Tower reported first 1,200 feet displaced due to construction. No displaced threshold markings on runway except light posts and three orange barrels on side of runway to indicate where actual landing zone started. Captain confused an arresting wire and marking across runway as the actual threshold. Fortunately, this crew’s aircraft incurred no damage. Others did not fare as well with their “short field”
