Don't worry mate! Frankly, If you have the permit in the office, and genuinely forgot, They should be "OK" with it to the degree of not going the full degree!!!! As you say you have a clean record! The Industry need people like you! And tbh need many of the posters on here! Its the ones who take the mick to say the least who they come down on! Like the 737 collision expert as told by Matty!
