Incident at Saskatoon, SK (Aerodrome - runway or taxiway surface condition, Aerodrome - operations)

Summary

1999-02-12: At 2130Z, a member of the Local Airport Authority advised Tower that Runway 09/27 was being NOTAMed closed for sweeping. There had been no prior consultation with Tower personnel, who had a number of a/c preparing to land on Runway 27. All except one a/c indicated that they could not accept Runway 33, which had a 10 knot, 90 degree crosswind at the time of the closure of Runway 27. Tower staff believe that a safety issue arose when the runway closure took place without co-ordination, with several smaller a/c operating in the vicinity of the airport, with limited crosswind landing capabilities. OPI - Aerodrome Safety UPDATE Aerodrome Safety reported that the runways were contaminated by ice and the airport maintenance crews worked on Runway 09/27 until they had cleaned it to a safe condition. Then work commenced on Runway 15/33 and with the help of warmer temperatures, maintenance was able to open this runway as well. As the day progressed, the temperatures began to fall, freezing the standing water on the runway. Because maintenance personnel were unable to obtain clearance from ATC to access Runway 09/27, the Airport Authority NOTAMed the runway closed for sweeping to remove the standing water to ensure ice did not re-form. The decision to close the runway was based on the fact that a short closure to sweep for water would have less operational impact than having ice on the runway, which would have a more significant impact on larger a/c. The Airport Authority made the decision in an attempt to satisfy all users without compromising safety.
