Confidence Rating: Accident investigation report completed and information captured
While the aircraft was conducting an ILS approach to runway 26 at EIKY with the autopilot engaged, difficulty was experienced in following the glideslope and the aircraft descended below the glide path. As the aircraft passed over a ridge on the approach the Enhanced Ground Proximity Warning System (EGPWS) activated and a go-around was initiated. Following this, a non-precision approach was flown which resulted in a successful landing. During that approach similar problems with the glideslope were experienced.

Probable Cause:
The absence of a Glideslope Antenna Deflector resulted in unstable glideslope signal reception which led to the autopilot descending the aircraft below the glide path in IMC.

Contributory Cause(s):
1. Ineffective monitoring and lack of situational awareness by the Flight Crew.
2. Inability of the EIKY ATC to monitor the aircraft due to lack of a radar display.
