I was P3 on a LHR-GLA trip, when climbing through about FL150, I noticed a slight whistling coming from the back of the flight deck. This gradually got louder, and I drew it to the attention of P1/P2. They thought they could both hear it and P1 scanned the pressn panel and said 'probably a loose door seal - put it in the book for GLA to look at'.
It gradually got louder. Passing about FL230, I noticed that I had left the manually operated dump valve fully open - left open for T/O and closed shortly therefafter. Very slowly, to prevent any surging, I wound it closed with my right foot. Sure enough the noise stopped. Passing about FL280 I asked P1 & P2 if they could still hear the noise, as I couldn't detect it any more.
They couldn't and commented that 'these door seals often sort themselves out'.
I then owned up, when P1 said he had done exactly the same as P3 on a Comet - but on that occasion, he hadn't noticed until the 'rubber jungle' appeared.
PMc, do you remember doing a block of work 28-31/1/80 including 5 CATIII approaches (@ LHR BFS & GLA), including, on one of the GLA's ex LHR 28R, #1 blowing up on rotation, with an incredibly long and loud graunching sound - we all thought the U/C had collapsed as I rotated - closing the R/W for an hour while it was swept of fan blades, with a subsequent 2 eng landing on 27L in about 800m? As if that wasn't enough, we ended the block with a night Malta! Apart from Malta, we reckoned we did't see the ground above 200' all week.
