Incident at 25 N of Calgary, AB

Summary

1997-09-18: NTM 440 was inbound to Calgary from Edmonton City Centre airport, and about 25 miles north, when the pilot reported sparks emanating from one of the propellors. The a/c was vectored for a close approach to Runway 28 and landed without further incident at 0218Z. The pilot was offered the ERS, but declined. The crew were operating the propellor anti-ice system at the time of the incident, and a post-landing inspection of the propellor showed that the electrical lead going to the anti-ice boot had unbonded from the propellor.This resulted in the lead being torn off while power was being applied, which caused the sparking. Further examination also revealed the bonding glue was brittle and did not secure the lead as it should have. The company is replacing the lead and adhesive, and will return the a/c to service when completed.
