N6475Q

Aviation, , , , ,

N25ES has now been determined by the insurance assessor as a total loss and the club is in the process of finding a replacement 172. Steve was supportive when I asked if I could fly the club’s 1981 Cessna 152 (N6475Q) in the interest of staying in touch with my flying skills. I flew the 152 for the first time on July 24 to get a feel for the plane. I had not remembered to charge the batteries on my GoPro the previous night so there is no video archive from that first-time experience.

N6475Q is different from N25ES in many ways. For starters, it is a 2-seater aircraft (vs. 4-seat) and has a significantly lighter empty weight of 1165lbs (vs. 1459lbs). The plane is very sensitive to control inputs because of its light weight and the ride is also bumpier as it is easily tossed around by wind. The seats feel like they are almost at floor level with the legs pretty much extended straight ahead to the rudder pedals. I found it harder to get in and out of the plane. Seats slide front-to-back and the backrest has a single reclining position flopping flat on the seat in order to reach the luggage compartment. Front seats on the 172 have height adjustment, seat back reclining angle adjustment and they slide front-to back. The engine is a 115hp Lycoming 0-235 (vs. 180hp Lycoming 0-320 series). The most noticeable difference was during climb outs after takeoff due to the weaker engine. I’m used to a regular climb on the 172 but the angle of attack has to be much shallower on the 152 in order to avoid a power-on stall. Roughly 67-70 kts Vy for the climb (vs. roughly 76-80 kts) and 60 kts on the landing approach (vs. 65 kts). Right after takeoff, we needed to level off to gain airspeed before climbing out.

I’m flying 75Q today again and we did a bunch of touch-and-go at Livermore. Towards the end we were switched to runway 25L and on the last approach, I was way too high and too fast so I did a go-around and requested tower to switch us to 25R for a full-stop.

Flaps + Power = Flower

A couple of days ago on June 30 we did a bunch of landings at Livermore. All them were decent or better, with one of them very good that Steve didn’t feel compelled to give me any instructions.

We started today with steep turns, power-off stall and then a simulated engine-out landing at Byron. On this approach we had quite a bit of altitude to lose. We tried a slip but that didn’t bring us down much because of headwinds. Then we tried S-turns to lose altitude. After 4 landings, we decided to head to New Jerusalem. It was a warm and cloudy day. The density altitude at Tracy was reported as 1600′. Reflecting on the landings at Byron I suggested that maybe extending downwind would have made it easier to land. Steve was emphatic (7:34 into the video) that that was not only necessary but it will provide more opportunities to botch a landing.

On the first landing at New Jerusalem, I came down hard and bounced up quite a bit. I didn’t react quickly so Steve shoved in the throttle (8:24) and did a go around. Rightfully he gave me an earful. The second landing was ok – flared up a little too much but was able to bring the plane down just fine. After two more good landings, Steve endorsed me to fly solo.

It was unnerving to hear Steve ask me to fly solo but once I got into the cockpit and started the preparations, all such nervousness dissipated. During the flight there was so much to mentally manage that there was no time to feel nervous. I felt ready to handle it with all the training I’d received. The first landing was alright but on the second landing I bounced. And bounced high. Thankfully Steve’s words must have stuck in the back of my mind because I immediately pushed the throttle forward and did a go-around. The nose wanted to point way high up with full flaps deployed for the landing and I remember pushing forward hard on the yoke to fly nearly level and build up airspeed before climbing and slowly retracting the flaps a notch at a time. Perhaps I came in too fast and too flat causing the serious bounce. Since I did a go-around, I decided to do two more landings for a total of 4. They were not great but I managed to make them stick. The rest of the flight back home was uneventful.

This unfortunately ended up being my last flight on N25ES. In the following week another member of my flying club flew the plane and while practicing touch-and-go at Livermore bounced hard on a landing. The plane porpoised but the pilot did not attempt a go-around expecting to salvage the landing. The nose gear touched down first and the prop stuck the tarmac. The pilot was fortunately alright. He was a low-time pilot (having recently earned his private pilot’s license on the Cessna 152 and only a couple of hours of experience on the 172) and didn’t realize the seriousness of what had just happened. He did a few more touch-and-go before calling it quits. Later inspection revealed that the tip of one prop had broken off and the firewall had buckled. The plane ended up as a total loss and an insurance claim. The club has started a search for a replacement 172.
