Narrative: We were at our cruise altitude of FL370. That's when we noticed little brown lights coming from where the glare shield meets the windshield.  As we were trying to determine what the problem was; a fire coming under the panel or where it was coming from. We started diverting and while the Captain was on the satcom that's when the windshield exploded and shattered. We decided to keep diverting because we did not know the structural integrity of the window.


Second narrative: A short time after leveling off at cruise; the first officer saw a light flickering on the left side of aircraft where the top of the instrument panel meets the windshield. We discussed the potential fire hazard and possibilities of where it was coming from. Initially we thought it might be coming from behind [the] instrument panel. It looked like three or four embers glowing; there was no arcing on windshield. Thinking it was a potential fire hazard; we decided to divert and called dispatch on satcom to coordinate and utilize their help to determine suitable airport for proximity and weather. During discussion with dispatcher; the left forward windshield shattered. Because we were not sure if there would be further complications such as pressurization problems or more damage; we continued divert. I turned off windshield heat on left side. The dispatcher sent a new release shortly after we started our diversion. During descent I transferred control of aircraft to the first officer since my view was obstructed. ATC asked if we needed further assistance and I let them know we did not at that time and that we were making a precautionary divert due to shattered windshield. Once windshield shattered; there was no further concern about potential fire hazard. The embers that were glowing disappeared. There was no smoke or fire indication.


Synopsis: B767-300 flight crew reported a failure of the Captain's windshield preceded by an apparent window heat malfunction. The crew diverted to the nearest suitable airport for landing.

Narrative: After reaching FL410 in attempt to avoid building convective activity; ATC instructed to descend and maintain FL340.  Response was unable for weather.  Controller asked if we were refusing to descend.  I responded; 'No; Ma'am; we are unable descend due to weather for 25 miles.'  There was a line of weather with tops indicating near FL500. We were on a 15 degree right vector to avoid weather and a descent in any direction would have been an unsafe decision.  The weather was actively building and FL410 was not on top.  We made the right decision to plan to maintain altitude rather than descend into convective activity. The Controller was not helpful whatsoever.  This is a common route flown by our company and we understand ATC LOAs; however safety was compromised by this particular Controller's response to our situation.  Many other aircraft were deviating and I don't believe she realized the extent of the relatively small; yet extensive line of thunderstorms and lightning on the Ohio-West Virginia border; likely west of her Center's airspace.




Synopsis: A corporate jet crew at FL410 in weather with cloud tops near FL500 declined to descend into the weather for safety reasons and in accordance with ATC LOA's.

Narrative: I was making a normal approach to Runway XXR on a solo flight. Winds were about 220 @ 6 mph at the time. After I had turned to base; ATC inquired if I had turned to base. I informed ATC that I had turned to base and at that point immediately needed to turn to final. ATC asked the plane at taxiway to hold position. Glide slope was normal. I was on centerline and airspeed was 85 mph. Final approach continued normally and as I crossed threshold; I reduced throttle to idle. The airplane landed firmly but did not bounce. When the nose wheel came down; I perceived a violent shaking of the nose wheel. The airplane began heading to the right side of the runway and I attempted to correct as normal. However; my corrections started a series of oscillations that grew in amplitude. The airplane was now headed in to the grass safety area after taxiway and I let the plane continue on its track for fear of flipping the plane. The airplane went into and out of the drainage ditch and came to a stop about 2-3 yards from taxiway X. I believe that one of the contributing factors to the event was task overload. This was my second solo flight and the additional load of ATC's inquiry; the follow on instructions to the other plane near my intended runway; and my focus toward the other aircraft may have used more attention than intended. I believe also that a greater emphasis overall on safe after landing roll would be good. In the FAA 'Airplane Flying Handbook'; after landing roll safety is addressed but does not receive the emphasis it deserves.




Synopsis: Student pilot reported loss of control after landing resulting in the aircraft departing the runway. The Student stated that distractions; while on final approach; were a primary cause for the loss of control.

Narrative: Upon starting descent from FL390 the amber boxed autopilot out of trim box appeared on both PFD's. After reviewing the abnormal checklist; the captain disconnected the autopilot and the aircraft made an uncommanded pitch up; which was arrested with manual control wheel pressure. Next; in the course of running the abnormal checklist the Captain discovered the pitch trim wheel was frozen and unable to be moved up or down with manual or electric trim. The Captain was able to maintain positive control of the aircraft using heavy forward pressure on the control wheel except for the brief moment when the autopilot was disconnected and we did not deviate from ATC instructions. Therefore; an emergency was not declared at the time.Upon reaching warmer air; around 11;000 MSL; the pitch trim freed up. A normal descent and landing at our destination airport followed.

Narrative: Climbing out at approximately 32;000 FT; a very loud bang was heard from the #1 engine.  The #1 engine instruments all displayed engine failure.  We declared an emergency; asked for a descent and vectors back to the departure airport; and made an uneventful visual approach.  The 59 minute flight felt like 10 minutes and we made every effort to cover all the bases.  The event went smoothly after careful and gentle communications with the Passengers and Flight Attendants.  The Flight Attendant did a marvelous job; and as Captain; I am running the event over and over; certainly there are details we could have done better.  All in all; it was gratifying to see our training kick in and support the decisions and actions that had to be made.


Second narrative: We heard a loud bang and immediately noticed that the number one engine readings were abnormal.  Most notably; the EGT gauge was showing an over temperature and a red indication.  We made one attempt to restart the engine using a Crossbleed start descending through 17;000 feet.  This was unsuccessful.  We completed the Engine Failure; One Engine Inoperative Approach and Landing checklists and landed.


Synopsis: A B737-700's number one engine failed in flight at 32;000 FT; an emergency was declared and the flight returned to the departure airport.

Narrative: While training a student pilot in ground reference maneuvers and lazy eights; we suffered a complete loss of power. engine restart procedures were executed and were unsuccessful. Our area of operation is in a humid coastal area. We are well versed in the use of carb heat and many times it is on for most of the flight. It was on continually this day. The area that we use for this training has many good hay meadows and pastures to complete a forced landing. Our landing was very good and we were able to land our Piper j3 with no damage or injuries whatsoever. We used less than 1/2 of the field to execute the forced landing.After the landing and securing the aircraft it was noticed that we had several areas below the carburetor where fuel was continually dripping out of the airbox in substantial amounts. We assumed the carb float was stuck and flooded the engine out.After disassembly of the Stromberg carburetor in the shop we found a good amount of small gray beads and flakes in the float bowl that could be easily crushed into a powder. one of these beads was lodged in the carburetor main fuel jet cutting off the fuel flow to the carburetor venturi. In maintenance during the [previous] annual the carburetor fuel bowl plug was removed and the fuel that was captured was visually inspected for contaminates. There were none. during an inspection of the disassembled carburetor after the forced landing it was found that this drain is not the lowest point in the fuel bowl and the only way to really be sure that all of these contaminates are out is to disassemble the carburetor. We also checked the carb fuel screen and it was clean. The gascolator had a small amount of what appeared to be rust and aluminum flakes in it but not enough to cause any issue. We purchased a lead test kit and tested the gray particles from the float bowl. They were found to be lead. We have been running nothing but locally sourced 100LL fuel for the past year. This event seemed to be a big enough deal that it was worth sharing to possibly prevent others from suffering a forced landing due to a similar issue.




Synopsis: J3 Instructor reported that contaminated fuel resulted in a loss of engine power followed by a forced landing.

Narrative: The taxi lights in RIC were upgraded to LED lights at some point over the last 3-4 years. The problem is; these lights aren't able to dim. When it is pitch black outside; it is very annoying and difficult to taxi with extremely bright taxi lights. The green taxi centerline lights are the worst. I have asked the Controller numerous times if they could dim them and have always been told that they are either not able to dim or they are already on the dimmest setting. I remember reading the FAA's Airplane Flying Handbook as a private pilot and it explained the need to let your eyes adapt to darkness and the keep them adapted. The bright taxi lights are an unnecessary hazard. While they might not directly cause an accident they are more than capable of being another link in the accident chain. Is there any way that these lights can be dimmed?




Synopsis: EMB-135 Captain reports RIC has LED taxiway lights which are too bright; creating a hazard; and Controllers are reportedly unable to dim.

Narrative: On 3 mile final to Runway 19 at TEB I saw a drone approximately 200 feet below us and 1/4 mile in front. We passed over drone without deviating from localizer or glideslope. Reported drone immediately to Tower. He responded that this is second sighting in 2 days. Drone was a twin rotor dark colored aircraft about 2-3 feet in length. It was in straight line with Runway 19 approach course. It appeared to be hovering then moved toward us on a 015 heading.

Narrative: While in cruise at FL340; ARTCC advised us that we were 5-6 miles off course. Upon hearing this; I noticed the FMA showing we were in HDG mode. ARTCC cleared us to turn back left and rejoin QXXX and we did. No other issues were noted. I was Pilot Monitoring for the flight and allowed myself to not be watching the FMA for a bit of time after level off at cruise altitude. I was looking at fuel calculations since ZZZ had weather all morning and was expecting to be slowed and possibly hold in route. I was noticing some discrepancy in my calculations based on fuel flow numbers and was looking into that. My MFD was on MFD advance (not FMS plan map) and my attention was diverted from monitoring the aircraft. I had chosen to do this once cruise flight was reached. The autopilot was on; and FMS was the active lateral mode. At some point; HDG mode became active. I hadn't noticed this selected and there was no reason for it to be selected as we had been on our FMS course and were not assigned a heading. I honestly do not know how HDG mode became the active mode. Alas; I was too distracted with fuel calculations and should have been watching the FMA closer.Even when busy with other items; in the future I will not turn my attention away from the FMA for so long.

Narrative: At about one hour into our flight; I had begun my rest in the bunk when I heard a bang similar to someone dropping something in the cockpit additionally the light in the crew rest momentarily went out and back on. The Captain alerted me; and I return to the cockpit to find numerous EICAS messages. The other FO [First Officer] was flying without autopilot or auto throttle. The Captain and I evaluated the messages and began to work the QRH for those messages. We discovered that the AC Number 3 and Number 4 DIST circuit breaker (35 amp) had tripped we did not reset. After completion of the QRH items we made the decision to return to ZZZZ. The other FO and I swap seats and I resumed duties as pilot flying. The flight was then vectored to a holding point to dump fuel to achieve our landing weight. We landed at ZZZZ without further incident. Crew executed good CRM and no recommendations could prevent in the future.

Narrative: While landing on Runway 3; after touchdown which was normal; I encountered a sudden; unexpected gust of wind that swerved the aircraft to the left before I had a chance to correct with right rudder. ATIS was calling wind at 300/12; although the surface winds had been gusty all morning. The aircraft went left off the runway and came to a sudden stop in the farm field mud.The aircraft sustained damage to the prop and; as a result of the strike; required an engine teardown and inspection. I was alone and unhurt and there was no property damage. Contributing cause might have been my low blood sugar causing my slow reaction to using opposite rudder; I had had a light breakfast that morning; but had been waiting all day as maintenance work was being performed.




Synopsis: During the landing rollout an unexpected gust of wind struck the reporter's C210 pulling it to the left and off the runway resulting in a prop strike.
