Background
On 9 April 2007 at approximately 1050 hours UTC, a Piper PA-28R-201T, Turbo Cherokee Arrow III, registration G-JMTT, experienced an event 9 nautical miles south of Oban (North Connel) Airport, Argyll and Bute, Scotland. The AAIB conducted a field investigation and published Bulletin No 6/2008, page 69, which contained four safety recommendations.
Correction
The AAIB issued a correction to Bulletin No 6/2008. The original safety recommendations were incorrectly numbered as 2007-002, 2007-003, 2007-004, and 2007-005. The correct numbering is 2008-002, 2008-003, 2008-004, and 2008-005.
Safety Recommendations
The following recommendations were included in the bulletin:
