OCCURRENCE LISTING --- Aircraft Below 5700kg
OCCURRENCES RECORDED BETWEEN 01 February 2015 and 28 February 2015
CESSNA F152 --- LYCOMING 235 FAMILY --- Circuit pattern - downwind
EGPG : Cumbernauld --- 21/02/2015 --- 201502141
Alleged poor airmanship demonstrated by C152(1) during circuit traffic pattern to R/W26. Aircraft infringes on established finals traffic.PA28 calls and reports rejoining the circuit and makes intentions of a right base join for touch and go's clear to the traffic in the area. The only traffic at the time was C152(1) in the circuit just starting the downwind leg. PA28 reports joining right base for 26 and C152(1) then reports downwind 26. PA28 completes a touch and go and C152(1) does a go around from their approach. At this point, C152(2) calls inbound from the north to rejoin the circuit from right base. PA28 then reports established downwind for another touch and go. This call is followed by C152(2) reporting joining base leg and is made aware of PA28 midfield downwind. C152(2) then reports right base for 26 and PA28 reports turning right base at the water features, which is an unofficial turning point in the circuit due to noise abatement. C152(1) reports late downwind and asks PA28 to make clear his intentions to which PA28 replies that they are turning right base 26 for a further touch and go. C152(2) reports final to land. C152(1) instructor then calls PA28 over the radio and states that they (PA28) are, "way outside the circuit" and that they, C152(1), were going to position number two in traffic. C152(1) then prematurely turns right base which puts PA28 on their left hand side. PA28 turns and reports established on a 4 mile final for 26 with C152(1) in front on a 1 mile final which put them number two in traffic. Then, C152(1) turns final and goes in front of PA28 and behind C152(2). This put three aircraft on finals within 3 miles of each other. The PIC of PA28 made an avoidance orbit on finals as he felt that safety had been compromised
