Yet another airline mishap. Wheel falls off of plane in San Francisco. Damages cars.

oldman, didn't you fly for United?

I read the article and watched the videos available online. I was thinking (like the cop in me) that suppose whoever put the wheel on the plane left it loose intentionally. Is there also a criminal investigation performed by the NTSB?

We all know that we do have doctors performing surgery that probably shouldn't even being operating on dogs and they are called out for any surgery they screw up and sometimes some of those screwed up surgeries end up being reported as criminal acts.

I would hate to think or find out that we have airplane mechanics that knowing mess up the mechanical issues on an airplane, but again, I suppose anything is possible.
Yeah, like a disgruntled employee. Well that's a scary thought! I wonder where these investigations will lead and if any of the investigators are thinking like you 911. Too many maintenance issue mishaps lately. Are they not training their techs properly? Carelessness that can cause hundreds to die should not be tolerated.

I'm still stunned at the variety of problems/issues. It's like someone is trying to find something different to sabotage or something.
 

IN my estimation, SF members should be MUCH MORE WORRIED by the number of flying transport truck wheel incidents on your Inter State highways, than the number of aircraft tires that MAY fall off.

With the razor thin profit margins that transport trucking companies have to work with, combined with the very poor levels of driver training in the USA, the number of deaths and injuries that happen are rising fast. The fault is usually a combination of improperly installed tire/rim combinations, plus a lack of proper DAILY inspections by the drivers of the wheel nuts .

The Ontario Provincial Police did a huge Province wide commercial truck safety blitz in 2022, that found that the biggest contributing factor ( for detached tires/rims ) was when a roadside tire replacement on a transport truck was done in the cold months of winter, the air compressors on the tire repair trucks did NOT provide enough air pressure, to safely secure the lug nuts to the rims.

A double tire/rim combination on a tractor trailer weighs more than 500 pounds, so when it comes loose at highway speeds, it can hit your car at 70 mph, and kill you. NEVER DRIVE NEXT TO A 18 Wheeler, pass it and get clear, as soon as you possibly can. My source ? Over 2 million miles of accident free driving in 57 years as a licensed commercial driver, including ten years driving an Ambulance in the largest city in my country. JimB.
 
Another plane just had a landing mishap ! Coming in for landing, the landing gear collapsed on this passenger plane. Everyone had to be evacuated with the emergency landing measures, and the people are fine. It almost seems like something is happening at least every week with planes now, not crashes, just serious malfunctions like this, that could be deadly.

When the pilot lowers the landing gear, he should get three green lights to let him or her know that all three gears are down and "locked." If even one of the gears don't lock, the plane cannot be landed without following the checklist. For example, maybe the bulb is just burned out. Sometimes, pilots have an extra couple of bulbs and breakers in their flight bag. (I carried a few.) The pilot takes out the bulb not lighting and switches it with a bulb that does light. If the bulb lights and the suspect bulb doesn't light, the pilot can be sure that the bulb is burned out.

If the bulb still doesn't light, the pilot may be able to lift the plate in the floor of the cockpit and crawl down into the hole (what we call the hell hole because it's very cold and dirty) and use the crank to hand crank the gear down until the light comes on. It takes a lot of energy to crank the gear down and a lot of time.

The three bulbs that light up when the gear is lowered represent the three landing gears. Two under the center of the plane (1 left and 1 right) and one for the nose gear. I never experienced an episode of the gear not locking when lowered. I have done it while in training. It isn't a pleasant job. Suppose all three gears don't retract after takeoff? Now what do you do? Yes, we have a checklist for that condition also.
 
I've flown in and out of SFO also.

Again, just glad no one was hurt on the plane or ground. The airline should pay for those employees cars vs. their insurance company.

I was driving from Indiana to Maine and was on the freeway
when a tractor trailor decided to pass me, just as he got even
with my car the right front tire blew out!~~~~~~ TALK about
needing dry drawers!!!! I backed off and he went into the medium to save his truck from wrecking....I parked a ways
in front of him....he walked up and gave me a sip out of his
pint....and boy I needed it.....

If it was the right front tire that blew out...He would have swerved to the right, not into the center median. In any case, you have just made my original point, don't let a 18 wheeler stay next to your vehicle, either pass it or slow down as it passes you. Limit the time you are next to any big truck .

I have experienced this a few times. I traveled the turnpike and interstates for 10’s of thousands of miles while on patrol. I can remember twice of it happening. The first time it happened, I thought someone fired a shotgun at my car, but then I smelled the burnt rubber and the all the debris laying on the road in my rear view mirror. I made a quick u-turn and went back to where all the chunks of rubber was laying, turned on my lights and closed the lane until we had removed all the road gators.

Road Gators are what we call the huge junks of rubber laying on the road from a blowout. Too many semis use retreads on their trailers and with all the heat those tires build up is what causes the rubber to separate and blowout.
 
Another west coast plane incident where a United Boeing landed missing a panel.

United Airlines Boeing plane loses external panel in flight

They landed ok and was actually discovered on a post flight inspection.

Are the suppliers of rivets, bolts, screws supplying defective product? Is United buying defective replacement parts or from a different supplier than the rest of the industry?(alot incidents on United flights)

While patrolling the Turnpike and the Interstates here in Pennsylvania, I investigated a few accidents caused by tires or wheels with tires striking another vehicle. I probably investigated more accidents caused by vehicles hitting deer. I remember my first deer/vehicle accident. A man driving westbound and about 100 miles from the Ohio line in a Ford van hit a big buck on I-80 killing the man when the deer went through his windshield and the buck's antlers struck him in his face and neck. Not a pretty sight.
 
I will stand by my original feelings that when the president ordered all airline employees be vaccinated, is what caused at least some, if not most of what has been happening with the bad things going on in aviation by the airlines having to employee inexperienced mechanics and pilots. It’s like the old adage goes, “You pay for what you get.” You hire kids just out of jet engine repair school versus an employee with 20+ years experience, don’t expect the wheels to stay on the cart.

It does seem like a lot of these failures are maintenance related either from incomplete or careless service. Or done by poorly trained and yes experienced mechanics. Either that or Boeing is supplying them with things like defective fasteners ie bolts, screws, rivets etc. Wouldn't they have to be rated or higher grade than one finds at the local hardware store?

The vax mandates acted like sudden downsizing which is why the airlines didn't fight it as much as they should because they reduced their payroll.

And just like many industries there always those employees that know better or are looking for shortcuts ie in a hurry to do nothing. Did they measure the torque? Didn't bother to find or replace missing bolts? All the washers, seals, gaskets in place? Were the tools from Walmart?
 
Definitely a problem somewhere. As usual, when all is said and done, there is more said than done.

Suspect airline emphasis is on maintaining the schedule, not on maintaining the airframe.

I spent some time in the hangars during my early years. It would amaze me how intelligent a lot of the mechanics were. If they didn’t know or weren’t sure of what procedure to use to fix a certain mechanical item, they had (even back then) a full array of manuals that showed a step by step guide of how to make the repair. No hesitation on their part o use the manual. It gave me (as a pilot) a lot more confidence that when the plane had just been repaired and flown by an off duty pilot to test out the part repaired a lot more confidence.

If the mechanic wasn’t able to follow the manual, he would often ask for help from other mechanics that may have had the experience to make the repair and train the mechanic having difficulty to follow along and take notes, if he or she so wished to do. I don’t know if that’s being done today because much of what was in manuals back in my time is now available on line by the manufacturer of each part of the plane. Boeing or Airbus does the assembly, but the many vendors make the parts.

Back when I flew, one of the questionable vendors that I didn’t have a lot of faith in was Parker Hannifin, which made a lot of Boeings valves and cylinders. There were several recalls for their parts, so I was always glad to see that when a Parker Hannifin valve or cylinder was replaced, the plane was tested by an off duty pilot to prove the part and that the plane was airworthy. That was one of the best rules the FAA ever drew up. Read about United Flight 585, if interested. One of my friends that taught me a lot at United was killed in a crash caused by a PH valve failure.

This is what’s printed online by Wikipedia — “The rudder surface most likely deflected in a direction opposite to that commanded by the pilots as a result of a jam of the main rudder power control unit servo valve secondary slide to the servo valve housing offset from its neutral position and overtravel of the primary slide.” Check out who made the defective unit. That crash caused me a lot of missed sleep.”

Guess who made the defective valve?
 
And yet another problem day before yesterday. The piece of metal over the engine came off of a Southwest jet. It was visible to some passengers as it happened and one woman described how scary it was. This happened shortly after takeoff and the pilot returned to the airport right away after being notified.
