Location:5.5 nm E of Dublin Airport (EIDW) -   Ireland

Investigating agency: AAIU
The aircraft, an ATR 72-600, was approaching Dublin Airport (EIDW) following a scheduled passenger flight from Edinburgh Airport (EGPH) in the United Kingdom. During the intermediate descent prior to commencing the published instrument approach procedure for runway 28, the aircraft descended below the altitude assigned by the Air Traffic Control Officer (ATCO).
The‘Minimum Safe Altitude Warning’ (MSAW) activated on the ATCO’s radar screen to warn the ATCO about the aircraft’s continued descent.
The aircraft had descended to an altitude of 1,082 ft. The altitude of an aircraft at this point on the ILS glideslope for RWY 28 should have been 1,975 ft.
When contacted by the ATCO, the Commander initiated a missed approach, climbed to a safe altitude and obtained radar vectors for a second approach. The aircraft subsequently landed at EIDW without further incident.

Probable Cause:
While conducting an ILS approach, the aircraft was descended unintentionally to an altitude that triggered the ATC Minimum Safe Altitude Warning.
Contributory Cause(s)
1.The Flight Crew’s lack of experience on the ATR72 ‘-600’ aircraft.
2.The Commander became distracted by the manual operation of the TLU to the extent that the flight path was not adequately monitored.
3.There were inappropriate pitch inputs made to the Commander’s control column that caused the autopilot to disengage.
4.The level of cockpit communication and co-ordination between the Flight Crew was sub-optimal
