Location: St. Augustine, FL
Accident Number: ERA17LA300
Date & Time: 08/20/2017, 1120 EDT
Registration: N9431N
Aircraft: PIPER PA 28R-200
Aircraft Damage: Substantial
Defining Event: Loss of engine power (total)
Injuries: 2 Minor
Flight Conducted Under: Part 91: General Aviation - Instructional 

On August 20, 2017, about 1120 eastern daylight time, a Piper PA-28R-200, N9431N, was substantially damaged during a forced landing after takeoff from Northeast Florida Regional Airport (SGJ) St Augustine, Florida. The flight instructor and student pilot sustained minor injuries. The airplane was privately owned, and the instructional flight was operated under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed at the time, and no flight plan was filed for the local flight, which originated from SGJ about 1035.

According to the flight instructor, the purpose of the flight was to practice traffic pattern touch-and-go landings. The instructor said that during the run-up he told the student "not to forget to change the fuel tanks every 30 minutes." The flight instructor stated that they were on their fourth takeoff and were climbing through 500 ft when the engine started to "sputter." The flight instructor took control of the airplane, declared an emergency and landed the airplane in a marsh area.

According to the student pilot, as they were climbing through 500 ft, she switched the fuel tanks while climbing and the engine "failed." The student pilot did not recall which fuel tank she switchd to prior to the loss of engine power. She passed the controls over to the instructor to perform the emergency landing.

Examination of the airplane by a Federal Aviation Administration Inspector revealed the right wing and airframe was buckled. A cursory examination of the engine did not reveal any anomalies that would have precluded normal operation. Due to the airplane resting in the marsh the amount of fuel remaining in the wing tanks could not be determined. Prior to take off the airplane had a total of 25 gallons of fuel on board. According to the Lycoming engine operator's manual, the IO-360C series engine fuel consumption is 12.5 gallons per hour at performance cruise. The airplane was flown for about an hour prior to the loss of engine power.

A timely example of how moving the fuel selector is riskier than people think. There are several ways this can go wrong and result in fuel starvation.
Before switching tanks, pick out where you would land if the engine quit. It's a good exercise anyway, but will save time messing with the NRST button. If you don't like the answer, consider deferring the switch until you have an acceptable option.
Why on earth would you need to switch tanks every 30 minutes in the first place? How unbalanced is a Cherokee going to get? Not very. Just keep track of how much you burned out of each tank and get onto the best choice before you get down in the pattern.

I'm wondering what the position of the fuel selector valve was in? Was it against the stop or was it "in between" thus disrupting the fuel flow? Also, my instructor told me to not switch the tanks until we were at pattern altitude in case the engine died we could hopefully dead stick it in.

You have to switch tanks sometimes no matter what.

Best practice is to be well above but within glide distance of an airport and not at relatively low altitude such as a pattern.

That is not hard to achieve. Since I have flown low wing more recently, on a couple of occasions the engine has sputtered momentarily on a tank switch over. It causes me to think in a non-gravity fed fuel system some air is able to get into the fuel line between the valve and tank of the formerly unselected fuel line.

The fuel pump should be on to minimized the amount of liquid fuel disruption if air is present.

The respective POH should be the guide.

I would be interested to know if the PIC was used to flying Cessnas. When you switch tanks in a piper and go to the left tank its the fuel cut-off compared to a Cessna where it'll be a different wing. I've seen pilots mentally memorize the Cessna fuel selector and assume its the same in a Piper and unintentionally hit the fuel cut-off.

I should have clarified in my previous post about switching fuel tanks at pattern altitude. I meant when we're actually in the airport traffic pattern and switching the tanks on downwind that way if you lose an engine you just make a short approach and land easy peasy. You never want to switch tanks on climb-out.

Well that's something, but really, why are you messing with the fuel selector in the traffic pattern AT ALL. How badly planned is your flight that you would need to do that. The engine out landing is more dangerous than you might think, and I just don't see how taking risk gets you any big benefit.
