"Angels work overtime for new Captains." I heard this from a veteran Captain during my captain training ,and I experienced this first hand during my first 100 hours of left seat flying with a tyre problem and a TCAS RA.The thing that I am proud is that I havent missed a slot,yet.But I learned my lessons.
I had a nose wheel tyre which a metal luggage part stuck in it,I asked a techician to check if it is out of limits and he agreed with me so I decided to change it.They finished the work the passengers boarded we had 4 minuttes for the slot time so I asked him if he had removed the landing gear pins,he said he didnt used any and I check them and saw both 3 in the cockpit,also I asked the push back technician to visually look at the changed landing gear and they told me nothing unusual and everything looked fine.So we pushed back departed,flew all the way back to Istanbul from Stansted and parked to our gate.
As we leave the airplane technician in istanbul told me that he wanted to show something.There was a whole ""REMOVE BEFORE FLIGHT" flag was stuck between the tyre and nose wheel hub.We were surprised how it stuck in there and how someone-who is not blind-didnt see it.Lesson learned always check yourself even it is a licenced mechanic.
Second was a TCAS RA,caused by an ATC instuction to clear us and the climbing traffic to the same level.We were coming from FL 250 and requested descend.We recieved descent clearance to level 220 initially due to traffic, and we read it back as "decending level 220."I saw the opposite traffic on TCAS so I started descent with 1000 fpm to avoid nuisance TA.as we close to the other trafic TCAS sounded "Traffic Traffic" so further reduced descent rate to 700 fpm.few seconds later we heard "CLIMB CLIMB" and responded imidiately diconnect th AP and started climb,we climbed 600 feet and reported to ATC.Later we discovered that she cleared the climbing(different company similar callsign) traffic also to FL220.Lesson learned, be aware with the similar call signs in the vicinity.
Now as I reached to 200 hour mark I hope my angels has to work less and less everyday.
