This article is presenting a real experience. However, training for precautionary and
forced landing must be done under the guidance of a recognised flight
instructor and in a save area. ª Click on the images for a better resolution. Click on the picture on the left to get a

WHAT IF… WHERE DO YOU LAND? and CAN YOU MAKE IT? Those questions come out very often when we fly with flight
instructors. I am sure that many of
you appreciated the instructors’ advice and practiced precautionary and
forced landings with them on many occasions.
But, how many simulate those type of situations, ALONE and REGULARLY? Personally, I practice precautionary and forced landings once a while
and usually by choosing a direction for landing that places the airplane in a
more or less upwind position.
However, for the first time after 30 years of flying and during the
summer 2001, I had to do it for real, on regional highway 125, in a downwind
position and at the same time I had to do my approach by flying the contour
of a mountain. That day (Fathers day), I made a flight plan from Rockcliffe to a
private runway in the Laurentide area.
One hour to get there, one hour to come back and two hours in
reserve. I always review my fuel
consumption and in my first half hour of flight I realized that I was
consuming more than expected, considering that I had a tail wind. Every five minutes I recalculated the
consumption and this confirmed to me that I was burning more fuel than
normal. As I recalled, everything
else was working fine in the cockpit.
I was in a mountain area and for precaution, I diverted to Joliette
airfield that is more south and located in the St-Laurent valley. My first diagnostic was that I probably
did not close properly my fuel caps (C-150) and the fuel was being sucked out
from my wings. As soon as I changed
direction the fuel gauges dropped more rapidly. As I tried to give an emergency call, my radio flicked out and
I was sure that I was not able to reach the valley’s airfield or any farm
fields. I was right over mountains,
trees and lakes. The following sections present you with my decisions and reactions
during this event. As I did after the
fact, you will probably say “…in his place I would have done this or
that…”. Whatever, what is important
is that I succeeded to land safely, no one was hurt or injured and I was able
to fly back to my base with the same airplane before the end of the day, so I
can enjoy a good drink with my family in my home backyard :-) |

Making the right decision : I have to admit that I
panic for a moment. But rapidly I
checked outside and spotted highway 125.
The 125 is a two lane road, one way for each direction. Fortunately it is 4 lanes for few miles
like a SUPER highway. Knowing that
the likelihood of not having any electrical wires crossing that portion of
the road was very high I directed the airplane to that section of the
road. My plan was that if there was
enough room on the road I would land the airplane. If the traffic would have been too dense then my second option
was to climb as high as possible until the engine stop, if my diagnostic was
correct. The traffic was very dense. However, there was a mile or so, in
downwind direction, where there was no traffic at all and a quick look
further away on the road showed no more traffic coming in. So I decided to land the airplane right
there and merging with the highway traffic. |

Securing the approach : The wind was about 20 knots
and a mountain was between me and the portion of the road that I wanted to
land and I was expected a down draft from that position. I wanted to drop full flap but the flaps
did not work. I turned my Master off,
directed the airplane further over the highway and dive to speed up so I can
clear the traffic that was going in the direction of my landing stretch. This helped to clearly indicate to the car
drivers my intention to land. I glide
over the highway, flying alongside the mountain and in a curve path following
the highway curve. As soon as I finished
the curve my landing spot was right there.
Because of the mountains on each side of the road, the wind velocity
increased significantly and the airplane did not want to drop. I made a quick sideslip and touched one
wheel in the last quarter of the landing strip that I planned to use. At the end of the strip there was an other
curve and I concentrated on controlling the airplane right on the dotted
line. |

Concentrating on the commitment to land
safely : Unfortunately, at the end of that curve the road had
a descending slope eliminating the decreasing of the speed. I knew that the 4 lanes highway was
merging into a regular 2 way road and normally I would have succeeded to
finish my landing roll before that portion where the road merged. There were road indicators on each side of
the road announcing the merge and I was sure that my wing span would not
allow me to safely go between the signs.
A little bit of throttle and the airplane jumped over that obstacle. I pull the throttle back immediately
because I knew that electrical wires would cross the road soon (300 feet
away). |

Securing the people and the airplane : Finally, I was in a position to really stop the
airplane. I parked it on a little
street that I thought was a house’s driveway. The owner and some other citizens came to help to park the
airplane safely and outside the 125 traffic path. I checked to ensure that everything was safe and that no one
could move the airplane. A quick
inspection of my fuel tanks showed me that I still had fuel for 3 more
hours. Obviously, the problem was an
electrical one. |

Advising the authorities: I called immediately the Montréal FSS to close my
flight plan and to advise them that I had to land on a public road. The FSS called immediately the police
force and a patrol car got there within the next ten minutes. I gave a call to my wife before anyone
else does. Fortunately, I was able to
locate an aviation mechanic and got him to check out my plane within two
hours. He was not able to locate
precisely the problem but suggest me to simply keep my Master off, he would
also unconnect the battery and the alternator and suggest that I fly back
with no electrics. |

Preparing for departure: So, I gave a call to Montreal FSS to make my flight
plan and got back in my
airplane. With the help of the
mechanic, we started the engine manually.
The police force blocked the road and escorted me to a safe departure
area, on the opposite side of were I landed.
Getting back to the 4 way highway was not simple. I had to go around the side road obstacles
of the merging area. |

Positioning for take off : Now the wind was in the
right direction for me to take off.
However, I had to be careful of the downdraft created by the mountain
right in front of me. My decision
then was to follow the highway path until a safe altitude. In addition I looked around to spot all
the possible side road obstacles and ensured that I stayed in the middle of
the road all the way until airborne. |

Getting back to base : The take off was easier
than the landing. I kept my brakes
on, applied full throttle, start rolling and rapidly I was airborne and
climbing. I made a circle pass over
the home owner who helped me. That
was a sign for him to call my wife and to tell her that I had taken off
safely. |

CONCLUSION
I made it! However I
learned many new things: 1) I should
have practiced more downwind approaches, more precautionary and forced
landings. I think that I made a sharp
landing but I am sure that I would have been better if I would have practiced
more. 2) Call the
flying club or the owner If you do not own the airplane. Let the club decide and send an instructor
to fly the plane back. I was the
owner, so I made my own decisions. 3) Back to the
base, I was very surprised to see all the support from my colleague pilots
and mostly from the flying instructors who backed me with my decisions. 4) The airplane
was inspected and the Masters connections were found a little loose. It is likely what created the
problem. I made two hours and half of
flight test and then I went back to were I landed in the Laurentide with my
friend Philippe Quézel who took the aerial pictures. The other pictures were made when I
visited the home owner who was my guest at the Fathers day. Safe flying to all of you. |
