After 4 weeks of fog and inversion layer in the region, we finally had a few flyable days. Sadly the best of them were during the working week, but Sunday dawned with a stunning red sky, a high overcast and good visibility so my wife and I decided to make an attempt to fly around the "Catlins" - the wild south-east coast of the South Island. Our two previous attempts at this scenic flight were foiled by fog and rain... so we were hoping it would be a case of third time lucky.
The transit to Balclutha went fast with a 20 knot tailwind at 6,500' giving a steady 180 knot GS. The descent through the friction layer required some planning but the journey along the coast at 1500' was very smooth. The remote beaches and ancient volcanic landscape made for a beautiful flight. As we closed in on Invercargill we decided to request clearance to 5,500' and transit to Mossburn where we were planning on meeting friends and grabbing a coffee. As we levelled out at the approved altitude a sudden banging noise started up outside the aircraft. The engine was running perfectly, all indications were fine, there were no control issues but there was a very loud and very disconcerting death rattle outside. I just couldn't figure out what it was. I'd polished the aircraft on Saturday and as part of this exercise you're visually checking everything over, so I knew there were no panels loose, yet it sounded like something was flapping in the breeze. Weird. Oh well, nothing for it but to make an PAN call and declare an emergency. I slowed to 110 knots and we dawdled across to NZNV. The noise persisted. We were cleared straight in and were a little surprised to see a welcoming committee of four fire engines with their red lights flashing and looking like they were ready to rescue the heck out somebody. I felt a little inadequate. It must have been disappointing for them that we greased the wheeler and taxiied in normally.
The origin of the noise was the rubber strip on the wingroot fairing, which for reasons that are beyond me suddenly decided to pull itself out of position and beat itself against the fuselage. In my 700 hours of flying RV-6's I've never seen this happen before. This machine has 210 hours and it's never even hinted at moving previously. Strange. I removed all the screws (photo is taken as I was removing the fairing to reset the rubber strip), reinstalled the rubber and buttoned it all up again. My wife went to the cafe and spent up large on muffins and scones which we delivered to the Crash Fire Crew and Air Traffic Controller by way of thank-you, then we headed to Mossburn for a much needed brew. After a couple of local Cheese Rolls (a southern delicacy) and a pot of tea we flew the final 35 minute leg home via the Nevis Valley to another greasy landing at Cromwell. Aside from the rubber popping out the journey had been fantastic and the scenery was just beautiful.
I'm still at a loss to understand why this rubber strip suddenly decided to make a break for freedom. Strange. I could have done without the distraction though.
